Hi, I've got a little problem. I have burned plenty of DVD-Rs in the past, and have never had any problems with the DVDs themselves. However, today I bought a new spindle of 50 DVD-R discs, and my computer can't read any of them! I tried putting several into both my burner and my DVD-ROM drive, but neither could detect one of these discs. They are technically identical to earlier discs I have used: DVD-R, 4.7GB, 16x, etc. The only difference is the brand: I previously used Maxell, and these new discs are Memorex. It's not that it gives me an error message or anything. My computer simply ignores the discs, and acts as if the drive is empty. I don't see any reason why my computer doesn't like this brand of discs, so is there anything I can do other than go back to Maxell? How can I get my computer to read these discs?
