Mark,

I applied all patches. So far no any issues, however I think some HD 
movies I have now started to play OK.
Before patching I remember some of them have slowly creeping 
pixelization issue. Now it looks like issue gone. All those movies were 
playing OK in mplayer so creeping pixelization was definitely myth issue.
Now I will do long term tests and next days I will report how things are 
going.

Thanx again for Your work with backporting.

BTW: I backported MythUI notifications as I'm using them for VoIP caller 
ID, monitoring system CPU/GPU/Fans etc.
If You are interested - let me know - I'll upload patch to Your server.

Take care !
