Hello, I yust checked the SNR Level the DVBSky-Card providing with the drivers from dvbsky.net (media_build-bst-14-141106): # ./femon -a 0 using '/dev/dvb/adapter0/frontend0' FE: Montage DS3103/TS2022 (SAT) status 1f | signal 7323 | snr b064 | ber 00000000 | unc 00000000 | FE_HAS_LOCK # ./femon -a 1 using '/dev/dvb/adapter1/frontend0' FE: Montage DS3103/TS2022 (SAT) status 1f | signal 7a71 | snr 2a17 | ber 00000000 | unc 00000000 | FE_HAS_LOCK Looks "better" than with driver from linuxtv.org via git. And I don't have any sync problems or video / audio drops. I currently determined following: * Using the drivers from dvbsky.net the card is "Montage DS3103/TS2022" => Loading FW dvb-fe-ds3103.fw * With the drivers from linuxtv.org the card is "Montage M88DS3103" => Loading FW dvb-demod-m88ds3103.fw I'm a bit confused... perhaps if I use the linuxtv.org drivers, the card is recognized wrong and that's the problem?
