Or can I use some other program for recording (I > tried mencoder without success)? > i just try a guess. i don't use tzap. maybe tzap doesn't dump the relevant tables (PAT PMT) so VLC can't reconstruct the service. i see indeed only video and audio pids in the log. can you try to dump the complete transport stream using maybe dvbstream you can try with the one available in your linux distro, but if it does not work well you can try from the cvs source: http://sourceforge.net/projects/dvbtools/ get the code straight from the cvs because it's newer then the (old) release, when you have a binary, give this command: dvbstream -f 522000 -o -tm 8 8192 > /tmp/test.ts then after some time, break the application with CTRL-C. beware, this should be a 24Mbps stream, so it will waste some space in the disk! then feed it with vlc vlc /tmp/test.ts and if it works you can switch on every service of the mux with the menu Navigation. hope it helps. bye andrea venturi _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
