Thanks. I have major problems with that version 0.91 that is on that site. In 
fact, sometimes I can't even get it to index a file output by my Freestyle 
card. I don't have the indexing problems with 0.92pre3, but I do have broken 
audio after the first cutpoint. I don't have time now to dig back into this 
further but I'll check again when if I get a chance.

I also found that gop_fixup, which was written specifically to fix the broken 
timestamps left by GOPchop, didn't seem to have any impact on my results. 
Perhaps GOPchop has different results depending on the capture resolution? I 
don't see why that would be so, but assuming we are both using the same 
version I don't know why my results would be so different from yours.

Anyway, I consider you to be more fortunate that I, since I haven't gotten it 
to work. ;) However, avidemux2 has been doing a great job and seems much more 
feature-rich so I haven't been hurting lately. :)
