I use a similar setup and I'm able to watch "eurosport" after using the
correct parameters for frequency, srate, polarization, vid, and aid.
There are many different lists for these parameters on the net but most
are buggy (outdated?). After generating a recent list of channels using
dtv_scan on my own most problems were gone.

But nevertheless: I'm not able to watch *all* channels and I don't know
why either. dvbstream doesn't generate any output for them.

Additionally I have an other question:
What's the reason for some flickering effects? mplayer shows the mpeg
video/audio stream but sometimes some flickering occurs and the picture
is unsteady. Sometimes I get Segmentation Errors by mplayer due to
bad mpeg stream. I crosschecked this using a different DVB-S card and a
different SAT disc. Same ugly effects. Any hints...?
