Currently using PowerDVD decoder to watch live DVB-T 720P using EVR and DXVA via my HD2600. It works great except for occassional stuttering at irregular interval. Sometimes I can watch it for 5-10 minutes with absolutely no stuttering at all, and then it just stutters (very slightly but still) for a couple of seconds but sometimes up to a a minute or so. But then it just "settles" and I can continue watching with no problem for another 5, 10 or 15
minutes until it happens again...

The thing is, that it does not happen when I'm using CoreAVC or turn off DXVA in PowerDVD.
So the signal shoul not be to blame.

Also Ive tried DVBViewer with EVR - and there it never happen.

Recorded h.264 .ts also shows this behaviour inside MP. When running the same .ts recording in DVBViewer or in PowerDVD - it never happens.

And I really want to use my HD2600 to do the decoding, to offload my CPU.
