Hi computer experts, I have a technical question, and wondered if anyone here may have any answers.
I have a lot of homemade DVDs that I have made myself for a personal project recently. I also made "data back-up discs" of these recordings, in case anything ever happened to the recordings I made (data files of the recordings which fit many onto one disc as data, which you can then re-burn onto separate DVDs). However, somehow, which I cannot explain, I cannot find these back-up data discs ANYWHERE. It has been driving me crazy too, because it was a stack of about 13 or so DVDs and I cannot fathom how on Earth they have disappeared. Even while spring cleaning and reorganizing, I have found nothing, and I have combed all over my apartment.
Now, I've noticed when I put a homemade DVD into my computer, it doesn't just have the recording itself as one simple movie file. It has several different files, which I'm not experienced with, that I guess "fit together" to make the source disc (same as with the discs from question # 1 here as well), but what I was hoping was that I could pop in each disc, copy the recording to my hard drive, and re-make data discs by bundling up the recordings on 13 discs again as data files for back-ups. But the files that are "watchable" are 2 files that are about 30 minutes each, and 2 that are about 26 hours each (??) which I know is not possible; and those 2 files, when I click to play them, don't show anything.
Any advice on how to make data files from discs that you've already burned?
