Hi, I'm unable to get any data out of a new TechnoTrend C1500 budget card (SAA7146 w/ STV0297). While it seems to successfully tune, czap reports a suspicuously low s/n ratio (around 3000-4000 decimal, compared to a older C1.0 budget card which works fine and gets around 60000). And no video, audio, or anything else comes out. The "scan" utility won't find any services either. Here's a sample czap output: ~> czap -r -c channels.conf MTV3 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' reading channels from file '.mplayer/channels.conf' 15 MTV3:346000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_128:305:561:49 15 MTV3: f 346000000, s 6900000, i 2, fec 0, qam 4, v 0x131, a 0x231 status 1f | signal 033a | snr 0ee2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0339 | snr 0dea | ber 00000000 | unc 00000000 | FE_HAS_LOCK etc. And for the older C1.0 card: ~> czap -r -c channels.conf MTV3 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' 15 MTV3:346000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_128:305:561:49 15 MTV3: f 346000000, s 6900000, i 2, fec 0, qam 4, v 0x131, a 0x231 status 00 | signal b1b1 | snr c6c6 | ber 009ffff6 | unc ffffffff | status 1f | signal ffff | snr eded | ber 009ffff6 | unc ffffffff | FE_HAS_LOCK status 1f | signal ffff | snr ebeb | ber 009ffff6 | unc 00000000 | FE_HAS_LOCK I understand that this card has had problems with the current drivers tuning to QAM128 channels, which this is, as can be seen from the output. All channels I can test on are QAM128 so I can't say whether the problems relate to that. This is on Linux 2.6.13-rc6 and dvb-kernel CVS checkout from Monday. The same behaviour occurs whether or not I patch the stv0297 driver to disable corner detection for QAM128, as described a couple of weeks ago on this list. I'm perfectly willing to provide any debug data I can and test any patches. Thanks, Ville Vehvil?inen
