Try the scan tool from linuxtv-dvb-apps then it should tell you. It tries to tune to each one in turn and then emits a list of all the channels that you can tune to. http://linuxtv.org/downloads/ IIRC there may be a bug in the last released linuxtv-dvb-apps package which might cause scan to go get stuck retuning to the alternate transmitters indefinately. I believe this is fixed in CVS, but i've never had this problem myself. Jon
