I've been backing up my dvds using dvdbackup, dvdremaster, dvdimager, and disc utility on an ibook G4 with an external Pioneer 107 firewire drive (8X). Lots of fun and less trouble than I expected. The whole process takes around 1:20 per disc. What I'd like to do is eliminate the compression step, in order to reduce processing time and increase picture quality. Has anybody tried this using the new 9.4 double-sided blank dvds? Will disc utility recognize them? Will I have any control over where the disc gets chopped into side a and side b? I'd really appreciate any advice before I order a spindle. Thanks!
