This same system has no trouble playing analog tv, and the cpu
utilization when running the command below is ~10%. "wa" in top is
0.0%. I guess I'll go to the -dev list and lurk there a bit, see if i
see anyone who might appreciate my help in debugging.

I'm having similar fun with the NZ DTT tests. If the video is not
interlaced I can get near perfect playback with clear AAC audio. With the
interlaced streams the video seems to lag behind the Audio.

Nico - I'm seeing this on the test files I'd already uploaded to mplayerhq.

I now have a DVB-T card in a rig where I can do live stream testing rather
than using --dumpstream captures so hopefully I'll have some additional
feedback soon.
