[linux-dvb] Twinhan dtv express and linux 2.6.10

[Roberto Sebastiano]

Hi,
I have a Twinhan DTV Express I bought a couple of days ago, but
currently, I have problems getting it working properly.

Previously I had a Skystar2 that worked without problems.


Now, for the Twinhan I have this modules loaded (linux 2.6.10):
newdeal:/home/robs# lsmod
Module                  Size  Used by

tuner                  21796  0 
bttv                  153680  2 dvb_bt8xx,bt878

rtc                    12664  0 

And dmesg says:

bttv: driver version 0.9.15 loaded

Note the line bttv0 detected .. "DVB-T" .. maybe the card is getting
detected incorrectly ?


This is lspci:

Video Capture (rev 11)
0000:01:09.1 Multimedia controller: Brooktree Corporation Bt878 Audio

The card is exactly a "Twinhan DTV Sat-Express" (DVB-S), as stated on
the box


I have a channels.conf in the .mplayer directory, but I get this:

newdeal:/home/robs# mplayer "dvb://Italia 1"

The same with xine (but it exits with a less meaningfull message)


I can only see the sat channels doing:
newdeal:/home/robs# szap -r "Italia 1"
reading channels from file '/root/.szap/channels.conf' zapping to 948
'Italia 1':
