I have to say you have a lot of channels over there what I can see from scan result [1]. Those channels which says "tuning failed" are channels where is no transmission and those "filter timeout pid" means there is ta ransmission and demod locks. Here in Finland we have only ~4 MUX DVB-T and maybe other 4 for DVB-T2. It is then actually working quite well from the developer point of view (as demod loses lock when antenna is unplugged). It means tuner and demodular are working but interface (transport stream interface, TS IF) between demod and USB-bridge is still broken. I tried to look again your sniff if I can see what it does just before streaming starts, but unfortunately there is no any mention about those streaming packets (isoc packets where picture stream is going). Did you remove those yourself? [1] http://pyther.net/a/digivox_atsc/patch3/scan.txt regards Antti -- http://palosaari.fi/
