Can you give an commandline example where i can feed a52dec with _any_
stereo-pcm/mp3-data and it makes 5.1 sound? So far i understand this program 
can only play ac3-frames just like ac3dec, if your mpeg-stream does'nt have 
it you hear nothing - unfortunately except Pro7 actually nobody has the money 
to send such streams - or maybe they are reluctant to buy a licence 
themselfes ?-)


Maybe it's just as Onno mentioned - "legal reasons" :-(

I simply think, that a software-solution to this is more flexible and can be 
adapted so that it works _reasonable_ with any data, depending on if it is 
just stereo or dolby you can switch to make it sound right, in case of a 
piece of hardware (not even cheap) you are bound to what it thinks it 
detected is correct... did'nt i buy for an 5.1 sound-card? should'nt there be 
already the license be paid to do dolby-decoding with it?
