[mythtv] DVB audio rate fixed?

[Paul Woodward]

Hi Kenneth,

I'm using MythTV-0.13. ffmpeg isn't installed on my box.

I'm slightly puzzled. The backend seems fine - no errors at all, it's only the front end that complains about excess audio.

I can also play the stream using:
dvbstream -f529833333 -cr3_4 -qam16 -ps 204 443 -o | mplayer -
and it's perfect.

What does the front end use to decode/play the stream?

Thanks, Paul
