Sorry about the multiple posts, I allways get paranoid that a single post will fall through the cracks... I've had the best luck with Memorex DVD-r media of all the brands. Imation DVD-r worked very well until recently when almost every single dvd I burned would have errors about 12 minutes into the movie. The Comp USA brand was decent as well. The only real problem media for me was the generic stuff that I made the mistake of ordering.
As far as the media I used for the diagnostic test. I tried everything I had which was my memorex drd-r blanks, my phillips cd-r blanks, one of the imation dvd-r blanks, A stor bought music CD, one of my kids PC games, and a store dought DVD. I was thinking about trying to use the plextools that came with the drive but they would probably do no good since it can't read anything.
Luckily, my PX48/24/48A is still working so I'm not without a cdr burner but I hesitate to even talk about it since it is only 2 months older than the 708A...
From what I gather on this site I was fairly lucky to have mine last as long as it did since it was built during a period of high failure issues. This is according to a handful of posts I found while scouring the board. by the way, the drive was dated September, 2003 with a TLA of 0002. I probably got close to 200 burns from it... well thanks for listening and if anyone has any tips I'd appreciate them.
By the way, I was looking into a BenQ drive. Does anyone have an opinion on their products?
