Hi Hans, It looks like your signal is quite weak. I can see values of 5700 with my antenna, and when using the card in a windows machine, it complained about too weak signal now and then. Here is my tzap output: [root@thay linux-2.6.11.8]# /usr/local/src/dvb-apps/util/szap/tzap TV4 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' reading channels from file '/root/.tzap/channels.conf' tuning to 554000000 Hz video pid 0x0419, audio pid 0x0418 status 00 | signal 0000 | snr 0000 | ber deadbeef | unc deadbeef | status 1f | signal 5700 | snr 3200 | ber deadbeef | unc deadbeef | FE_HAS_LOCK status 1f | signal 5700 | snr 3c00 | ber deadbeef | unc deadbeef | FE_HAS_LOCK status 1f | signal 5700 | snr 3200 | ber deadbeef | unc deadbeef | FE_HAS_LOCK status 1f | signal 5700 | snr 3200 | ber deadbeef | unc deadbeef | FE_HAS_LOCK status 1f | signal 5700 | snr 3200 | ber deadbeef | unc deadbeef | FE_HAS_LOCK I've just ordered a CAM-module so next week the adventure continues...
