> Has anyone successfully used gopchop generated files with dvdauthor ?

Yes, but I use a heavily patched gopchop. And I extract the audio and video separately.

My gut feel is that your problem is due to gopchop-1.1.7"s inability to snip exactly at frame boundaries. I sent Kees Cook a patchset a while ago that included a patch that can do this (and he forwarded it to the mailing list, but it looks like you can"t retrieve the patchset from sourceforge), but it probably _still_ won"t work for you since my patchset didn"t leave 2048-byte DVD-complient frames, nor was it smart it enough to snip the audio in the same way, too, nor did it handle DVD NAV packs.

I"m still trying to figure out if the audio is a big issue or not. I do think the 2048-byte packets, as well as the code"s ignorance of NAV packs will ultimately break it.

If you want to try my patchset (it"s against gopchop-1.1.3, some, but not all of the patches were included in 1.1.7) you can get it at:

But like I said, I don"t expect it to work (sorry).
