I have just confirmed that the
DVDfab 2 pass issue for PSP is not related to other software. I installed DVDFab Platinum 4.1.2.0 on a clean install of XP SP2 and I still had problem. I'm always unable to do 2 passes with the PSP 3.3+ setting on full length movies. I have had the issues on 4 different machines with 4 different DVD drives so I find it very hard to believe that it is hardware related.
I have been public about this issue for over 3 months (including Fengtao's contact form) and it has not been addressed. I wish the bug would be addressed.
When I google the expression that is creating the problem ("rce->new_qscale >= 0") it comes up with a bunch of stuff. It looks like some people are trying to deal with a 2 pass vbv handling issue.
Could some other people confirm that there is a problem? 90312 could you try 2 pass on a 80+ minute film?
