If the answer to this question could be discovered, then problem solved.  So,
what you are suggesting is VDR is not doing something that mplayer is doing that
fixes the problem.  Hmmmmmm... so then it is not a driver or firmware issue
after all?? Could we agree that much? :) This has been back and forth for a long
 long time with the drivers development team and Klaus. hehe.
