</div> OTA, eh? Yes. I have similar problems myself. Anything OTA that has<br>
visible blockiness tends to make the trunk internal player crash. I can<br>
play the recordings back fine with any other player.<br>

</div> HDPVR recordings (assuming you are in the US) are much more system<br>
intensive than OTA recordings. MPEG2 is easy. h264 can be downright hard.<br>

After some experimenting I now understand how much more intensive H264 is to decode than mpeg2 which I guess is why so much attention has been paid to VDPAU and the NVIDIA driver. Until I got the HD-PVR working I haven't had to deal with it at all. Just goes to prove the rule of inverse knowledge ("the less you know about something, the more it can do").<br>
