I've been trying to capture videos from my DirectV reciever to my PC using a Hauppauge HD-PVR 2 1512. I seem to be able to capture fine but there is a problem with playback using XBMC. The PVR captures AVC in TS,M2TS, and MP4 containers. I've tried them all with various bit rates and resolutions but non seem to play back properly on my ATV2 runing XBMC 12.3.
I've even tried capturing 480p at a very low bitrate. While the playback is somewhat better it's still choppy and buffers a lot.
Here is the info for a sample I captured:

I've been reading forums and trying all different types of settings pretty much all day and I'm at a total loss here.
I suspect it may be something to do with the codec the Hauppauge captures with but that's just a guess.
Anyone have any ideas why this is causing me such grief?
