This sounds like a fps issue.

You could try adding -ofps <desired fps> to the command line and see if 
that fixes it.

Also,  using -mc 0 and/or -noskip can cause av sync issues, if MEncoder 
needs to
drop frames to keep av sync those options will prevent this.
(especially if your source is variable frame rate)
So it may pay to try the -ofps without -mc 0 and -noskip on the command 
line.
