Sounds like it would be easiest to not use threads and in fact disable it in the x2whatever encoder, i would hate to have to stick with that though as I do have two cpus... better than segfaults tough. I am using custom cflags on that, though I've never had a problem with that. I think what I'll try is disabling threading support in the apps, try again. If that fails, move away from custom-cflags in mplayer. So many factors :) Thanks. -- "When you walk across the fields with your mind pure and holy, then from all the stones, and all growing things, and all animals, the sparks of their soul come out and cling to you.
