Hello,

I am not sure if I am sending this to the right list or whether it would be 
better to ask the VDR list.

I have a Siemens DVB-s card and Hauppauge Nova-t DVB card.  I do not have 
satellite access yet but  I am hoping to use the TV card to receive digital 
terrestrial signals and use the hardware decoding features on the  DVB-s card 
to run VDR and play DVDs, etc (at least until I get a satellite dish).    
According to this site, this should be possible:
http://www.linuxstb.org/dvb-t/

I can receive digital terrestrial signals fine from the Crystal Palace 
transmitter and stream it across my network:
 dvbstream -f 481833 -v 2827 -a 2828;
and then
dumprtp | ts2pes 2827 2828 | mplayer -cache 2000 -
gets me channel 4.

However I am not having much luck getting output to go through the DVB-s 
card.  When I try vdr, the terminal window goes blank and i don't get 
anything on the tv.  Similarly, doing
 MPlayer-0.90pre1/mplayer -vo mpegpes teststream.mpeg2
gets me the following result:
MPlayer 0.90pre1.1-3.0.4 (C) 2000-2002 Arpad Gereoffy (see DOCS!)

Does anyone have any suggestions as to how i can get the DVB-s card's video 
output to work.  Thanks in advance for any advice.
