I've had *real* issues playing back MP3 files. For example: tunes ending part way through, single tunes appearing as multiple tracks, playback of two different tracks at the same time, skipping between two tunes and ignoring half the stuff on a disk to name but a few. Also I've not yet figured how the 596 decides on the play order.
All the disks play perfectly on my (cheap) Aiwa car stereo.
I use Nero 5.5 and I've tried different media (CDR, CD/RW, 650Mb and 700Mb) but not licked the problems yet. I suppose I should spend some time trying different burning programs and speeds to see if that makes any difference.
Maybe the new firmware will sort it out?
