Looks like you've just joined the mailing list, so you may have missed my post earlier. It should be relevant no matter where you are since you'll need to create your own channels.conf . There is a channels.conf-dvbt-berlin in linuxtv-dvb-1.0.1/apps/szap/ which you may find useful to edit or copy to ~/.tzap/channels.conf . Instead of trying 'scan' or 'dvbtune' use the tzap program.

Thanks to Alex Woods for this Driver!

Good Luck. Hope this helps.

Since you have the modules compiled and running here is how to get make it do something useful:

>To actually use the device you'll need to create a channels.conf file. If like me you aren't in an area where someone has provided theirs, then you'll need to make one by hand, as the scan utility doesn't work with the driver yet, as I found out. If you need to create one you'll need the appropriate values for the channel name, frequency, transmission mode, guard interval, QAM, FEC, inversion, audio and video pid. Most of these values are the same so editing an old one is easiest. The values you need can be found by running the box to a tv and selecting the information from the setup menu (before starting the modules connected to a pc as this will put the box into a slave mode until you pull the power and reset it). Once you have your channels.conf you can store it in ~/.tzap/channels.conf and use the tzap utility.  This is in the 'apps/szap/' in the DVB CVS folder or  linuxtv-dvb-1.0.1 will probably work too. To view the picture you'll need to use ts2ps along with mplayer. This is where I had the mose trouble as this is found in libdvb from http://metzlerbros.org/dvb/index.html. This wouldn't compile under 2.6 since it has a dependency on linuxtv-dvb being installed and this doesn't like my 2.6 kernel. I compiled this under 2.4 and installed the binaries onto my 2.6 machine and it worked. I think all that is needed it to create a link from DVB/include/linux/dvb to /usr/include/linux/.

Copy your channels.conf to ~/.xine/channels.conf Running xine with the gui you can click on dvb button and it should tune to the first channel in your conf file. There is a small N for navigation and clicking on the down button lets me scroll through the channels. I can only get video and it is always having buffering troubles with severe audio stutter. If anyone has advice on how to fix this, it would be much appreciated, but mplayer works perfectly as long as I'm not maxing out the CPU by compiling at the same time.
