Keep all the files if you want full proper playback capability. The ifo's
contain important navigation info. Considerng they are really really small
compared to the 700MB vobs being created, its kinda stupid to even worry
about it. If you are always only going to play it back from teh hard drive,
its not even necessary to do any of this. Previously I think you posted
about wanting to save it to 700MB cds, which again , based on the current
price of dvd burners and media, is a total waste of time. Its 2005, deal
with it...
