Hey Vincent,
does the dvds card give you a V4L2 interface or some other thing that is independant?
well, as far as i understood latest drivers from linuxtv are designed to merge v4l and dvb interfaces. i found that kaffeine will look for dvb device in sth like /video/dvb/... (i don't have the computer in front of me right now so i am pretty sure the path is a bit wrong). btw, using kaffeine is nice because it can scan automatically satellite channels...
xawtv seems to recognize the dvb device just like anyother v4l device. even Gem e.g. seems to recognize the dvb device. but in both cases (xawtv and Gem) i can't get any image...
hey. I wrote a little DVB reader and channel switcher this summer. As far as I know, once you have the drivers up and running, you will have some devices created under /dev/dvb/adapter0
If you have a decent card with hardware MPEG2 decoding, you will have an extra device there. If you have an el cheapo card like I do, without hardware decoding, you just get the mpeg2 stream under /dev/dvb/adapter0/dvr0
The first device I mentioned that is the decodec MPEG2 stream should be able to be opened like a v4l device (not sure about this though). The second device I mentioned, /dev/dvb/adapter0/dvr0, should be able to be opened as a regular mpeg2 file. Either way, you should be able to get it somehow into GEM or PDP.
The difficult part will probably be to get your channels list and to switch channels without loosing sync.
If you want some half-assed C++ code, let me know.
best -august.

yes. the full featured (ff) dvb-s cards directly use the video interface of linux, and thus you can watch it with xawtv, etc ....
without that, you need to decode the transport stream first.
in any case, you need a backend to control your dvb card, i.e. switch channels, select the propper sub-streams, etc....
i highly recommend you to install vdr:
also see here: http://www.vdr-wiki.de/wiki/index.php/Hauptseite
i use it for my own ff card, and im very happy with it, especially if you have it extended with pluging & patched it to look nice ;-) furthermore, you can control vdr via a network connection, so you can have full controll in pd over vdr, in theory ...
in case of a full featured card, also make sure that you have an actual firmware installed....
greets,
chris
