Yes, I am using VSO engine. I just tried to back up Alexander across two DVDs and got the same error. The "split title menu" said there was 3.85GB on Disc 1 and 3.6GB on Disc 2. I'm very new to this stuff and this program. Is there something I'm missing? I tried the free DVDAnywhere trial on the first dvd that was giving me trouble and it copied it compressed to one disc with no problem.
