Which of the two MediaPortal pvr addons are you using? "MediaPortal (ffmpeg)" or the "MediaPortal (TSreader)" plugin?
The ffmpeg version relies on rtsp streaming @ tvserver + ffmpeg playback @ xbmc side. This version shows for me and many other users the same artifacts as you are describing (with and without dxva). As PVR addon developer, I cannot do much about that because its an ffmpeg issue.
Hopefully the new ffmpeg version that will be used in the next XBMC release will perform better. In the current xbmc git, rtsp playback is completely broken under Windows, so I can't say at the moment whether that will solve your issue. I'm currently looking into the ffmpeg rtsp playback issues with help from Elupus.
The TSReader version uses a completely different approach to play the TV stream: no rtsp streaming and direct playback from the MediaPortal TSBuffer files (using the same code as MediaPortal)
If your problem is caused by the TSReader version, I'm very interested in a XBMC debug log file posted on pastebin. It could be that the stream transfer from the addon to XBMC needs some additional buffering.
Further questions: does the problem also occur when you disable DXVA? Is this an SD channel or an HD channel?
