I want to make a new video from a crappy DVD. I want to make some clips with mencoder so I can use them in kdenlive. I have tried with the mplayer's copy video codec, so that the frames are copied verbatim. But when I export the clip (to DV), the video and the sound (I'm using pcm@48khtz for the same reason: not to lose information) don't match together. The sound outpaces the video for about 5-8 seconds after just 80 seconds of play. So... is that because I'm using the "copy" output codec and so (maybe), there's no video header in the file? :?: Could I use another? I need a lossless one (or almost), remember.
This are the codes I have available with mencoder:
$ mencoder -ovc help -oac help MEncoder 2:1.0~rc1-0ubuntu12 (C) 2000-2006 MPlayer Team CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (Family: 15, Model: 3, Stepping: 3) CPUflags: Type: 15 MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection.

Also, here's the mplayer output for one of the clips I made from the video:
