Hello list,
First, I hope Im in the correct list with my dvbstream problem.
I want to stream live tv over network with dvbstream. my problem is, 
that i dont reviece any data, because dvbstream cant lock to the correct 
frequency (or so).
But I can watch TV with all other apps (expect vdr, but thats another 
story), so I have really no idea what to do.
I use the following config:
- Cinergy 1200 DVB-C card
- dvb drivers included w/ linux- 2.6.12.5
- dvbstream-0.5 and the current (as of october 25th, 2005) cvs version

some output:
## dvbstram-cvs
ventura dvbstream-cvs # ./dvbstream -f 522000000 -s 6900 160 161
