Btw here is a neat trick for G5 owners:
1) Get a DTS cable (optical digital) and plug the output socket into the input socket on the back of your G5.
2) From System Preferences select audio in and audio out as digital.
3) Start up GarageBand and create a new Band file named as whatever you want to record and create a new track appropriate to waht you are recording (i.e for a Billy Connolly DVD I selected Live Performance -> Stereo).
4) Put in a DVD and using the DVD player get to the start of what you want to record (you will have to do this visually), pause the DVD and the press Record in GarageBand and Play on the DVD player.
5) Sit back and wait until you are past the end of what you want to record then stop recording.
Now just switch the system audio back and fine tune the audio in GarageBand. (i.e get the levels right, add reverb etc)
A two hour DVD audio track will fill around a Gb btw so do it in several slices otherwise GarageBand will choke on it, around 500Mb per track seems to be it's limit of usability on a G5 with 1.5Gb of RAM.
In GarageBand cut the track into 10 minute segments and export each segment to iTunes, then use iTunes to convert each segment into Mp3 (aiming at around 10 Mbytes per Mp3 file) and at the same time numbering them as Track 01, Track 02 etc.
Now just delete all the AIFF files from iTune and export the whole thing (i.e all the Mp3 files) to your iPod and you now have your very own film soundtrack on the iPod in segments that will load into Ram and play continously. I have 3 whole put DVDs of stand up comedy routines on my iPod using this method plus the music from the Lord of the rings extended version.
PS remember to give the tracks an album name (select all the tracks in iTunes, right click or ctrl-mouse and select Get Info) so that they are easy to find afterwards.
