the "incredibly annoying vertical jitter" I believe is the "bob" for which bob was named. Interestingly, it disappears when using XvMC.
I am currently using SW decode with no deinterlace because I am driving a 1080i display, which wants interlace input. When I switch to 720p, I use SW decode and kerneldeint because of the "bob" issue...
