I captured a DV stream using dvgrab and am using mencoder to convert it from AVI (type 2) to MPEG4, but every 10th frame, starting from the 12th, I get a "skip frame!!!" message.

What is this all about?

sounds like bad audio/video samplerate at headers... upload sample, attach mencoder -v log etc etc... as usual.... argh we are still unable to read in users' mind or terminal...

I have a 30 second clip I can upload, but it's 150MB. I am running Linux kernel 2.4.17 with the low latency (kernel preemption) patches. Earlier today I was running stock kernel 2.4.16. I am running the latest CVS mplayer, compiled with GCC 2.95.4 by typing "debian/rules clean binary".
