I have the problem of burning a DVD, and it will play on my computer and only on an Apex, but not be readable in any other standalone I can find, and this was with good media, more than one brand. This has happened with both my A04 and A03, with 4 different burning apps, and with different firmware. I know this is a burning problem, don't know if it has something to do with my IDE chain, whether or not the burner is slave or master, I just don't know, I just know its not software or media. If anyone has an idea lets hear it. I have an Asus motherboard running Win XP, Athlon XP 1800. Oh, and this doesn't happen to every disk I burn, but enough to tick me off real good! I have already tried switching from DMA to PIO mode, it didn't help! I would say I lose 1 disk in every 3 or 4.
