[vdr] FF-card and AC3

I don't know when this has broken, or is it even VDR related.. My FF-card was without signal at winter and i've been using only budget-card that time (FF-card as SPDIF and tv out only)..

Now i put signal back to FF-card and noticed that Dobly Digital audio tracks doesn't work (with budget they work fine, using FF-card as SPDIF and tv output only). I got external decoder, and it says only PCM (and no sound) when selecting DD-soundtrack. When watching same channel with budget card, Dolby soundtrack works fine.

Firmware is F62623 (test-av 1.34) and driver is v4l-dvb from mercurial few weeks ago.
