I tested with and without -mc 0 -noskip and got basically the same
result.  Lag in both cases.  So I take it from your surprise, that
this should work well with most files, and this is probably an
exceptional case?  I uploaded 3 files to /MPlayer/incoming/video_lag:
the script (basically only contains the mplayer command line
executed), the source file and the destination file.  Hope it's
helpful :-)
