On the audio/video sync issue... still have it. The new video card works great and I do notice an improvement in the reduction of the number of dropped frames (still get some but very low numbers).
Does your sync issue is only with HD-PVR ? or with 24p source too ? Maybe you can give https://forum.team-mediaportal.com/...renderer-better-video-playback-quality-84441/ a try !
Just my two cents.
I shall give it a whirl and report back. Thanks!
UPDATE: I'll restrict my posts on this topic to the MP Audio Renderer thead: https://forum.team-mediaportal.com/general-development-no-feature-request-here-48/mediaportal-audio-renderer-better-video-playback-quality-84441/
>>> Last word ;-) I installed it and notice that the MP Audio Renderer is adjusting the a/v sync (I think) ... so I'm hopeful that will be my solution.
