Congrats andy8 Glad you've got the dvd working, bet you've been kickin them out all weekend then. As for ac3 sound, haven't gone down that road yet. However if ur just backing up dvd's, then using dvd2one, pinnacle instant copy, ifoedit then u can keep the audio streams. Anyway nice one.
you might have VTS_01.ifo ect but as far as i know you also need the .BUP to go with it otherwise it will play on a pc but not in a standalone. ive not tryed to do one yet ill let you know.
