I personally believe that quality differences in optical
cables are a myth created by the vendors of the more
expensive cables. I bought a DM 6 optical cable for my
DVD player from Reichelt. I have no problems at all with
it, the sound is excellent and there are no dropouts.
I think it should not be too hard to transmit the bits
without errors. As long as that is the case, what difference 
can a higher quality cable make (except for maybe looking
better)?

Is C-Media 8738 the chip name and Leadtek Winfast 4XSound
one card using the chip or is C-Media 8738 another similar
card altogether?

Great idea!
That means I do not have to switch receiver inputs when
I play back an AC3 recording.

Can I keep vdr running with the -a "ac3play" parameter all 
the time?

Thanks!
I'll go to Hamburg on Wednesday and get one.

Wonderful!
I'd appreciate this very much.

Thanks,
