I don’t have a W7 PC yet, so I can only speculate. Currently Podium does not call MMCSS, but I would expect it should be the audio driver that should set up its thread with MMCSS. It’s the audio driver that calls into Podium, and so the audio driver controls the thread. I could be mistaken though. Generally I will not recommend changing the registry as suggested in the topic you linked, unless you know how to undo your changes.
