HI!

I've a audio problem regarding the Eurosport 2 channel on astra (and as far as I've noticed ONLY with this channel).

If I use ffdshow (CCCP) audio codec I get no audio tuning to this channel (all other channels are fine).
If I use the PowerDVD8 audio codec I get audio on eurosport 2 and on all other channels.

Because I experience suttering TV using the PowerDVD audio codec I'd love to use ffdshow for audio.

Any Idea what to enable in ffdshow to get audio on eurosport 2, too?
