  Ok, I have opened the thing to see what it had inside. The chips I can
see are:

  + DibCom 7700B chip (though I only can find in their website a 7700P
one)
  + MT2060F chip
  + EPCOS X7350P chip

 So I think that this device (A808) has nothing to do with former A800
device from AverMedia. As they support Linux yet I am comfident we can
make it supported with a free driver as well, but I also think it is
going to take longer than expeected.

 I have some photos of device internals if you want to see them.

 Cheers,
