Well, there is far too little information.
Your command lines don't seem to match what you actually did and we
have no logs of neither the mencoder run nor the problematic playback.
However the possible issues are not using -ofps resulting in insane
frame rates being used (which will also make your files too large)
or the generated AVI file being > 2GB without ODML enabled.
