you should use the European Channel List with frequencies stored in './transponders/4000.ini', it is possible to create a new file of your own, for switzerland, there you should look at several pages, to find out transponder issues for switzerland. a helpful site should be
http://www.vdr-wiki.de/wiki/index.php?t ... .2F2006.29
for the beginning. look further down for more links in that vdr-wiki (a linux dvb-t software). or check the german forum, probably.
i had some other difficulties (Berlin, Germany channels) not being able to recieve VHF channels (up to 226,5 Mhz frequency, where it seems that dvbdream is not able to check the floating point numbers, i do not get any signal; I want dvbdream to scan 191,5 MHz; no! it just scans 191 MHz - very frustrating), although UHF work fine. I was not able fix it until now. other dvb-t software make it like dvbprog but they are not this stable like dvbdream....
