Hi All, I am having reception issues with this particular card, the problem manifests itself with missing video frames and popping sounds on the audio streams. As far as I can tell it only some channels do it, "Nine" and its multiplexes are the worst for it You can see that TZAP every now and reports some unc/ber: crystal:/usr/share/dvb/dvb-t# tzap -a 0 -c 0 "Nine Digital HD" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' reading channels from file '0' tuning to 191625000 Hz video pid 0x0200, audio pid 0x0000 status 00 | signal 0b28 |
