Hi everybody,

I'm trying using my DEC3000s with mythtv and kaffeine for accessing TPS
(french satellite channels set available on *Hot Bird 1/2/3/4/6 at 13.0°E).*

But, I'm unable to build a channel list, here is the log (similar
problem with kaffeine when scanning for channels):

jdu2 scan # ./dvbscan dvb-s/Hotbird-13.0E
scanning dvb-s/Hotbird-13.0E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12539000 H 27500000 3
>>> tune to: 12539:h:0:27500
WARNING: filter timeout pid 0x0011
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x0010
dumping lists (0 services)
Done.

I'm sure that antenna is OK since it works when DEC3000s is standalone
or/and DEC3000s is used with software provided by Hauppauge (on Win32).

Any idea?
Any way to guess what is wrong? Some tests to done?

For people who are (successfully) running DEC3000s with linux, could you
give me some feedback [on stability, features (that are missing), or
...]? Especially, stability with TPS (since even in standalone mode I
experience some troubles when changing channel (no image or no sound
until shutdown/restart the DEC3000s)?

Help would be greatly appreciated.

Johann
