Playback stuttering on 6.1

[litkaj]

I upgraded to 6.1 this past weekend and thus far am not terribly pleased. Aside from the background image that does not render very well at 1920x1080, my biggest complaint is that video playback now seems to drop frames every 30 seconds or so.

I'm not watching anything terribly difficult to decode ("DVD Standard Play" MPEG-2 recordings from a Hauppauge PVR-500, although MPEG-4 files also exhibit the same issue) and I have tested a few different decoders (nVidia, PowerDVD, Sage, & ffdshow). This is a problem that I had under older versions of SageTV but it was solved by enabling FSE mode. I checked and FSE is enabled, but it doesn't seem to be helping.

I checked out the properties file and noticed a few entries for thread priority of various components of the program. Does anyone have any suggestions as to what can be adjusted to make this problem go away?
