Which DVD-reader is recommended for verifying burnt dvds?

[tautau]

I have an NEC DVD-writer which, unfortunately, seems unable to verify the disks that it burns. A disk will burn successfully but any verifies I try to perform (with Beyond Compare; nero's cdspeed or other programs) will fail 50% of the way through the disk. However, the dvd's I burn play perfectly in standalone players.

Since I need a way of verifying my burns before I can archive them and since it isn't practical to watch every dvd from beginning to end in a standalone player to do so, I decided it would be best to buy a seperate dvd-reader drive and verify the disks using that.

So this is my question: Which dvd-reader drive is recommended for this sort of task? I need a drive that will handle many different types of disks well and that provides as high a quality of integrity checking as possible. I've heard a rumor that LiteOn drives are very good at this sort of thing. Can anyone give me their opinion on what dvd-reader drive is good for this? As all the dvd-reader drives are now extremely cheap the only real reason to choose one over another would be quality.

The best thing to do would be to research online. They used to have a DVD-ROM list on this site, back when it was DVDRHELP.COM. I don't see one now. That's what I used a couple of years ago when I needed one that would read DVD+R, which my DVD-ROM at the time would not read.

You might have to do a Google search for "DVD ROM list" or something and look at more than one site to compile your own list of DVD-ROMs. I suspect that today most of them read most disks, except maybe some home-burned DL ones and maybe DVD-RAM, unlike a couple of years ago, when you had to be more selective.

i can't remember any dvd-rom list...

Had the same problems with Nec writer (nd1300a), my dvd player could also play them but they were still coasters. I had to burn at 2x/2.4x to maker most DVDs readable, but still barely. Just assume that if your nec cant verify the disks they are coasters, and getting a DVD-rom will not change that. It is possible that some of your dvds will verify succesfully with an extremely god reader, but considered that a new burner cost only a little bit more than a dvd-rom i think you should get a new burner. If you want a burner that can possible read your nec-burned dvds then i can highly recommend dvr109, it reads almost anything with firmware 1.40. Mine can even read the semi-coasters from the nec (but only with firmware 1.40).

For DVD Video I don't trust any verifier. My process to ensure playability is Nero CD/DVD Speed Test (free download from ahead.com). If it shows a good steady curve with no spikes, the disk goes on the shelf. If there are any deviations, I use the read test in DVD Info Pro. If this comes up clean, again, the disk goes on the shelf. If not, it hangs from my pergola to scare off the birds. To date, this process has never failed me (touch wood)

DVD Info works with my NEC drive.

can someone explain what that graph from Nero speed/quality test ideally should look like and how much or the size of spike a failure should be to be considered coaster. uploading a good example with be very helpful
Thanks

Maybe? https://www.videohelp.com/cdwriters

OK. Maybe I am hallucinating. Maybe there never was a list of DVD-ROM drives. Somehow, I found some DVD-ROMS and their specifications regarding the types of disks they would read. Maybe it was a few Google searches or something.
If there never was one, it would have been good to have one. Especialy back when some DVD-ROMs would read DVD-R but not +R. Like I said, that's probably not a factor today.
In any case, tautau should do some self-research. This is probably better than asking for opinions here.

My understanding is that you should see a nice, gradual curve rising over time as the read speed increases. Any spike indicates an interruption to the read process, either because of a burn issue, a disk issue, or dust. Minor blips ( a couple of pixels) aren't usually an issue. Larger spikes could indicate a problem. If I see any spikes I perform a read test in DVD Info Pro. If it comes up clean, I consider the disk fit for consumption.
