Help, my DVD-R is somehow screwed up

Factual Questions
1

I was copying music videos from the 80’s to the late 90’s that I recorded from VHS to DVD. I have a Sanyo DRW-1000 DVD Video Recorder & 4 Head Hi-fi Stereo VCR. I recorded the videos, just fine. Because you can’t add chapter breaks unless recording in VR mode (for DVD-RW’s) I would record a video, stop, record the next, and so on, until I was done with the tape.

After that, I started naming each video title. I didn’t have time to do them all, and the next day, my wife took out the DVD to watch something else. Later on, I went to complete naming the videos. Now, until the disk is finalized, you can select a title and choose from three options: 1)Delete the selection, 2)Rename the selected title, 3)Play the selected title.

Half way through the process, I got to a video I wanted to watch again, so I chose to play the title. I got a black screen for a minute or so, then it ejected the DVD. Now, whenever I try to insert the DVD, it tries to read it, then spits it out telling me that it doesn’t recognize the DVD.

I tried putting the DVD in my wife’s computer, even though the Sony format many not be compatible, and the disk wasn’t finalized, just to see If I could save anything that way. All it did was lock up the computer until I ejected it.

I was stupid and threw away the original tape so if I can’t find a way to fix the DVD, the videos are gone and I’ll have to try and start from scatch. So if anybody can offer any help, it would be greatly appreciated. Oh, and I’ve looked over the disk closely and there’s no visible scratches or cracks, and I cleaned it with disk cleaning solution, so I don’t think that there’s anything physically wrong with the disk.

Well, it’s been a month. Any new developments?

I have the same thing happen sometimes, with DVDs from a particular batch Mr. Rilch bought when we were in Pittsburgh. For no apparent reason, the machine will refuse to recognize the disk. It always does, eventually, after patiently ejecting and reinserting the disk numerous times. All I can figure is, the calibration on the DVD tray must be very, very sensitive, and these disks are physically different in some way from the one we usually get, so they have to be put in juuuuuuust right. Or perhaps the machine itself is the problem.

Anyway, I can’t imagine what went wrong with your disk, if it is the disk and not the machine, unless…Are you absolutely sure you didn’t hit “delete all” some kind of way?

use a program like cd roller or isobuster and extract the data to your hardrive and burn it again. packet writing is notorious for losing data. the data is still on there and cd roller will get it 99% of the time.

Thanks for the advice but it might be too late. I think I threw it out a week or so ago, but I can’t exactly remember, so if I have it I’ll see if I can copy or, so to speak, revive it.
And I know I didn’t erase it because it’s not giving me a blank disk, it’s (the DVD recorder) trying to read the disk and then ejecting it telling me it doesn’t recognize it.
I’ve been able to get most of what I lost from other sources and hopefully I’ll get everything I lost, so this won’t be a complete loss.
