Frodo 12.1 Margo with fast channel switching - refresh rate

Hi Margo,

First, many thanks for your work on making the MP backend integration and improving channing switching times.
For a few days now I use the new pre-build version (xbmc-12.1-Frodo-margro.exe).
The improvement is huge indeed, however I noticed that it now takes longer for XBMC to adjust the refresh rate of my screen to the framerate of the stream.
Before, this was instant, as with movies, now it takes about ~five seconds after the stream is started (screen goes black for a second when changing refresh rate).

This alone is not realy an issue, it is a one time thing when zapping, but often I use the following method:
Watching TV at 50Hz > Open guide > RR will go back to 60Hz > select a channel > wait 2 second for stream to start > stream plays ~5 seconds > xbmc changes RR of my screen.
I know it is a minor issue compared to the huge improvement made on channel switching time, but it is annoying and I was wondering if there is a way to fix it?

Cheers,
MiC
