Ok, If I understood you correctly, you're talking about only plain DiSEqC switch, with no polarity/tone management. Polarity and tone switching are done by LNB's. Recently, I found a branded switch, which was unable to decode a DiSEqC commands while polarity was on horizontal (18V). Maybe is the same situation, maybe not. That's why I asked you to check the polarity/tone settings of the channels while switching to a different channel on a different satellite. _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
