Hi Thomas,

It seems that the picture is okay, and your sound doesn't work and it is 

I'd suggest to try to make sound work under Windows first, if it is 
Windows XP.

My thought is that if the card does not work under Windows, can it work 
under Linux?
At least we can conclude that the hardware works, if the device works 
fully under Windows.

If Twinhan has not not tested and designed the device to work for you, 
there might be some
incompatibility problem also on hardware. Usually devices don't just work.
They work if and only if they are designed and tested to work.

I don't have a CAM module. I checked from the digital cable TV, that
here in Finland, sometimes the sound is encrypted and sometimes it is 
not encrypted while
the picture is encrypted. It might also be that the picture is sometimes 
not encrypted. EPG is not encrypted.
