Hi Tilman,

well, I think no, because I checked the installation directly with the  
maintainer of cx88.

With the cx88 executable I can scan DVB-T channels, I can capture into a  
file, and I can capture a DVB-T transmission into a udp port and at the  
same time receive and diplay that transmission from the udp port with  
mplayer (OK, not perfect quality, but...). That shows for me that DVB  
works here.

First, would like to be able, but I am not a developer/programmer, I can  
only contribute with testing, translating, documentation.

Second, I think to have what you have mentioned above - a general  
interface for DVB Hardware in FreeBSD - would be the right approach for  
all drivers (coming from left side) and viewer programs (coming from right  
side), as a standard interface. Better than trying to adapt to a situation  
that most probably is only valid accidently and specifically at this point  
in time.

Just a thought and I have no clue what the process would be in FreeBSD to  
come to such a standard interface.

Best regards
Axel
