PC freeze while using ProgDVB and a game

#1
Hi,
this program works fine, with subtitles and all with just the default settings. I have Windows 7 64bit and I am currently running the latest ProgDVB 64bit version.

I actually have not tried this yet with this version, but it used to be so that when I first launched a rather modern game (DX10) and plan to let it run in background doing some automated task ingame, and then launch ProgDVB, the computer freezes completely.

There must be some conflict now but I do not know what it might be? Can anyone give a hint, please?
