Thanks, this solved the problem. Now I'm able to tune and watch channels but I noticed an interesting thing: I'm running femon, the signal strength and snr seems ok, if I run szap then the signal strength falling down (but the channel is tuned): coda:/usr/src/linuxtv-dvb-apps-1.1.1/util/szap$ ./femon using '/dev/dvb/adapter0/frontend0'FE: STB0899 Multistandard (SAT)status 00 | signal 9bc4 | snr 0804 | ber 00000000 | unc bf82ea28 | status 00 | signal 9bc4 | snr 0804 | ber 00000000 | unc bf82ea28 | status 00 | signal 9bc4 | snr 0804 | ber 00000000 | unc bf82ea28 | status 00 | signal 9bc4 | snr 0804 | ber 00000000 | unc bf82ea28 | status 00 | signal 9bc4 | snr 0804 | ber 00000000 | unc bf82ea28 | status 1e | signal 00a0 | snr 0091 | ber 00000000 | unc bf82ea28 | FE_HAS_LOCKstatus 1e | signal 009d | snr 0093 | ber 00000000 | unc bf82ea28 | FE_HAS_LOCKstatus 1e | signal 009d | snr 0090 | ber 00000000 | unc bf82ea28 | FE_HAS_LOCKstatus 1e | signal 009d | snr 0091 | ber 00000000 | unc bf82ea28 | FE_HAS_LOCK I read that some cards support only 8 bits of data in strength & snr. what I don't understand is why the strength is dropped to 8 bits if tuned. (I'm newbie, I hope that I interpreted the data well.)
