I've emerged this and have been using it for a couple days now. I get a few crashes here and there, but I think that may be related to Q-dvdauthor itself. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I'd like to second this request. qdvdauthor works great on my athlon64 box (64bit build) ... in fact, I authored a DVD start to finish with qdvdauthor and kino, all on a 64bit build. It also runs just fine on my dual opteron at work.
in CVS, thanks
