Do these registry changes for Hauppauge. . .

Do anything?

This is from the SageTV website:
[[
What can I do to improve the performance of the video quality? (For Hauppauge users)
Try out our registry performance increase for Hauppauge users. This works when you are also using the InterVideo NonCSS Video Decoder for Hauppauge as the selected Video Decoder in SageTV Recorder/SageTV.

Just change these registry settings to 1 while SageTV is shutdown:
HKLM\Software\Intervideo\Custom\Hauppauge\VideoDec\Dxva
HKLM\Software\Intervideo\Custom\Hauppauge\VideoDec\Hwmc

For the newer decoders the location is:
HKLM\Software\IviSDK4Hauppauge\Common\VideoDec\Dxva
HKLM\Software\IviSDK4Hauppauge\Common\VideoDec\Hwmc
]]

Also, should I be using the "InterVideo NonCSS Video Decoder"?

They reduce the cpu usage used by the "InterVideo NonCSS Video Decoder" when playing back MPEG2 videos. It is equivalent to enabling hardware accelleration in the configuration of other MPEG2 decoders.

This will only really be noticable on older systems (~1Ghz or less), as on newer systems the CPU can decode MPEG2 without breaking into a sweat!

It may also require that the Overlay renderer is selected in Sage (depending on your video card).

Well, I am using the PVR-350 with TV-out, so I don't really think that applies. Does it?
