I haven't followed this thread from the beginning, but did you say whatkind of DVB hardware you have? I know the Nova-TD stick is a bit picky. Too strong a signal will causethe behavior you describe on this device. On my Nova-TD, using a goodantenna will yield no data stream (but a 100% signal), whereas if I usethe little mobile antenna that came with the stick, I get a stream butmpeg artefacts in the picture (due to low signal). I would try attenuating the signal (or removing amplifiers) or adifferent antenna. I would also give it a shot (since you're usingmplayer to test) to use mplayer to control the whole scenario (tune,stream-on, demux, decode and display). Try the following command: mplayer dvb://1@TV6 Using the TV6 channel will avoid any obstacles by the channel namecontaining extended-ascii (Ö) and space ... TV6 should be an unencryptedchannel and on the same MUX as TV4, even in the Öresund region ;) // J On Sat, 2008-02-09 at 01:28 +0100, Per Blomqvist wrote:> The channel isn't encrypted.> (I have tested with many public chanels, that I know isnt encrypted. > Cant get any video out)> > Im Debian-tesing user, and this is a freshly installed system.
