Wahoo! 8) Managed to get DVD playback working pretty flawlessly under Linux, using Xine and the libcss plugin. Providing the DVDs are R1 or R0, that is... I only get the sound with R2 DVDs (and the audio skips, too...) I guess it's still early days yet though, although I did spot a patch for R2 compatibility on my travels (if only I could remember where...)
Anyway. I'm knackered so I'm having an early night 8)
