I'm begining to suspect that, too...I need to try out all the discs realy quick. However, I just found it odd that the maxell cd-rs work. I tried reading it in both of my drives, each of which have had no problem with TDK. I have a lite-on dvd-rw drive, and a cd-rw that came with my dell(don't know what brand).

Also, some are in audio and those work fine.

This is quite perplexing...
