Can My Computer Read a Dvd +r

Approximately 5 years ago, I spent time transferring a load of camcorder videos on pocket-size tapes to to DVD's. At the time I remember the model I used was like to JVC's DR-MV1S where I could plug in my sony handycam and connected a lead that went directly into the recorder. I burnt the dvd'southward on both DVD-RW and DVD-R formats. I know they played back fine on the dvd role player. However, that dvd histrion bankrupt so I am left with the DVD's but cannot play them.
I have tried playing them in my Windows 10 laptop but it simply whirs round and is not recognised, and also in our only dvd player (one in a combination Grundig tv) but that too doesn't recognise it and ejects information technology after a few seconds of whirring.
I desperately want to sentry these recorded home movies equally they contain precious family memories. Is at that place anyway I can play other than trying to notice the JVC recorder, would anyone have the skills to transfer what is on these DVD's to another format for viewing?
Thanks

Unlike music CDs, DVDs are simply estimator data discs with media files written on them. So even if the figurer couldn't play the videos, he should at least be able to browse the files on the discs. Information technology sounds like he cannot even do that.
I run into two possibilities hither: Your DVD burner used some sort of proprietary format that but information technology could read. Your only solution then would be to find the aforementioned or similar model which tin can read the format. Then catechumen information technology to another more widely supported format (preferably purely digital files). This isn't unheard of. Hollywood saw these standalone DVD burners as a digital version of the VCR, and they hated VCRs with a passion. And then they potent-armed a lot of manufacturers into crippling them so you couldn't, for example, burn down alive TV evidence broadcasts to DVD and share them with your friends.
Or the DVD burner did not make very good burns. Optical media works by burning a pigsty into a dye layer. A laser shines through the hole and bounces off a cogitating layer indicating a 1. If there is no hole, the dye layer absorbs the laser, there is no reflection, indicating a 0. (Or the other way effectually - I ever forget which is which). No dye is a perfect absorber however, and so there'southward always a tiny bit of reflectance. The difference betwixt the amount of reflected light amplification by stimulated emission of radiation light when at that place is a hole and there isn't is effectively the indicate to noise ratio.
Mass-produced DVDs (and CDs) physically change the reflective layer itself, and have something like a 1000:ane SNR (I don't recall exactly, these are ballpark order of magnitude figures from a very hazy retentiveness). DVD-Rs accept to apply a photosensitive dye to allow a write laser to fire a hole, just not sensitive enough to burn when hitting with the read laser. These are more difficult to produce and then are a lot more reflective, and the SNR is merely like 100:one. DVD-RWs are the worst. They use a phase change material instead of a dye layer, and their SNR is on the club of 10:i.
If the DVD burner is weak or marginal, it might non burn a very large hole. Maybe the writing laser is weak or doesn't stay on long enough, and non enough dye is etched to make a full-size pigsty. This further reduces the amount of reflected light when there is a hole, decreasing the SNR even more than. A DVD burner/reader manufacturer who knows this may install reading circuitry that is more sensitive to recoup. The DVD will play on that player, but won't on others considering their readers are not sensitive plenty to distinguish the 1s from the 0s.
So if this second reason is why you cannot read the DVDs, then you'll simply have to proceed trying them on different players until you notice ane that works. If the drive lets you lot control the read speed, try setting it to 1x. If you can discover someone with a Plextor, try that. Plextor was widely regarded as the Rolls Royce of CD and DVD bulldoze manufacturers because they overdesigned them with superior (and overpriced) components. The defended DVD players (for abode video) tend to exist meliorate at reading than computer DVD burners, so endeavour them in all of your friends' Television set DVD players.
And I don't retrieve the problem is media deposition. 5 years is not very long by optical media standards. ten years I'd expect to encounter a few problems, 20 years I'd expect to encounter a lot of problems. Just problems after 5 years would exist very unusual.

They sell a super-duper optical role player, what's the make name I forget somebody help me, is like usd$200-500 depending on features but information technology's said to read anything. I dunno, that maybe your last resort. I would definitely go to a local video transfer store and run across if they tin read your disc, am assuming they accept more "robust" equipment so at to the lowest degree u know.

Unlike music CDs, DVDs are just figurer data discs with media files written on them. So even if the estimator couldn't play the videos, he should at least be able to scan the files on the discs. It sounds like he cannot even do that.
I see two possibilities hither: Your DVD burner used some sort of proprietary format that only it could read. Your only solution then would be to find the same or similar model which tin read the format. Then convert it to another more widely supported format (preferably purely digital files). This isn't unheard of. Hollywood saw these standalone DVD burners as a digital version of the VCR, and they hated VCRs with a passion. And then they strong-armed a lot of manufacturers into crippling them so you couldn't, for instance, fire live Telly bear witness broadcasts to DVD and share them with your friends.
Or the DVD burner did not make very expert burns. Optical media works by burning a hole into a dye layer. A laser shines through the hole and bounces off a reflective layer indicating a 1. If there is no pigsty, the dye layer absorbs the laser, there is no reflection, indicating a 0. (Or the other manner around - I always forget which is which). No dye is a perfect absorber all the same, so there's always a tiny bit of reflectance. The departure between the amount of reflected laser light when there is a hole and there isn't is effectively the signal to noise ratio.
Mass-produced DVDs (and CDs) physically alter the reflective layer itself, and have something like a chiliad:1 SNR (I don't recollect exactly, these are ballpark order of magnitude figures from a very hazy retentivity). DVD-Rs have to use a photosensitive dye to permit a write laser to fire a hole, just not sensitive plenty to burn when hit with the read laser. These are more than difficult to produce so are a lot more than reflective, and the SNR is only like 100:1. DVD-RWs are the worst. They use a phase modify material instead of a dye layer, and their SNR is on the lodge of 10:1.
If the DVD burner is weak or marginal, information technology might non burn down a very big hole. Maybe the writing laser is weak or doesn't stay on long enough, and not enough dye is etched to make a full-size pigsty. This farther reduces the amount of reflected light when there is a hole, decreasing the SNR even more. A DVD burner/reader manufacturer who knows this may install reading circuitry that is more sensitive to compensate. The DVD will play on that player, but won't on others because their readers are not sensitive enough to distinguish the 1s from the 0s.
So if this 2d reason is why you cannot read the DVDs, and so yous'll just have to continue trying them on different players until yous notice one that works. If the drive lets you control the read speed, effort setting it to 1x. If you tin find someone with a Plextor, try that. Plextor was widely regarded as the Rolls Royce of CD and DVD bulldoze manufacturers because they overdesigned them with superior (and overpriced) components. The dedicated DVD players (for domicile video) tend to be better at reading than computer DVD burners, and then endeavour them in all of your friends' Tv set DVD players.
And I don't think the problem is media deposition. 5 years is non very long past optical media standards. 10 years I'd expect to run into a few issues, twenty years I'd expect to see a lot of problems. But bug later on 5 years would exist very unusual.

I believe you lot simply did not FINALIZE your DVDs when y'all recorded them. If you didn't finalize them, then yous cannot use them on annihilation else than a JVC recorder. You volition need to purchase some other JVC DVD recorder, finalize your discs, and then you will be able to read them elsewhere.
DVDs need to exist finalized when recorded to be used on another player or a PC. If you practice non do this, information technology will be unreadable practically everywhere. The disc are basically written in Raw data, without any Lead In / Lead Out. Null short of the same exact model or brand can read the data, sadly.
I've seen many people do this error over the years. Yous demand to read the manual for DVD recorders, or you lot'll be in trouble if y'all didn't finalize and it breaks.

I always thought this was automatic for single-session recorders and manually to close out a multi-session disc, and I always thought even with an unclosed disc, you should exist able to at to the lowest degree browse it. Sounds similar his is only doing an endless seek.

Not on a abode DVD recorder, as the OP had. The DISC needs to be finalized or it volition non read elsewhere. They simply do non even make a session at all, they merely write RAW or proprietary data.
Since there is no usable lead in/out data, a computer DVD drive can't read the information. Information technology will just spin endlessly. Aforementioned with another brand of DVD recorder.
