HD recordings on a HDPVR can be up to of 13.5mbps, but the real kicker
is that they are single sliced. That means you will only be able to use
one core to decode it (until the ffmpeg-mt stuff comes through), and you
will need a fairly beefy processor to do that bitrate single threaded.
Are you sure your CPU had spare idle time, and did not have one core
