I too have issues with HDTV in Australia. I'm using KWorld cards which
have pretty much identical hardware to your Fusion. (BTW I hope you have
the Fusion Plus and not the Lite.)
- Seven HD has choppy audio with audio buffer underrun messages to
the console at a rate of a few per second. I'm using ALSA drivers
and Myth's ALSA audio support.
- ABC HD (which is different from ABC in the US, please note!)
works OK if I go directly to it when starting HDTV, else the audio
is choppy. I get some ffmpeg errors spit out on the console every
few seconds even when the audio is working fine; they are ac-tex
errors and the like.
- SBS HD has breaking picture and audio, with lots of ffmpeg errors.
I didn't try 9 or 10.
It doesn't appear to be CPU-bound; if anything while watching Seven with
breaking audio (but OK picture) CPU usage seems lower than other stations.
I have an XP 2600+, GF4 MX440 video (not using XvMC).
I have been content with the digital SD stations until now but recently
bought an HDTV, so would like to get this going at some point. I can
help debug but don't know where to start.
