Hi, Our DVB-T network has once more been changed here in Karlstad, Sweden. Once more I noticed strange behaviour with scan (atrpms linuxtv-dvb-apps ver 1.1.1.2_20070420.fc7) and tzap. It used to work without a problem before. After creating a scan file with fec high, low and guard interval set to auto I was able to scan a Mux for channels and create a channels.conf. I knew the frequency(650MHz), the bandwidth(8MHz), the modulation (QAM64) and the transmission-mode (8k). However in trying to use the resulting channels.conf with tzap, I never get a lock. I didn't know the FEC or guard interval part. Now I have 2 different types of DVB-T cards. One Nova T 500 PCI Dib0700(Yes I know, I have the latest firmware) and a TerraTec Cinergy 1200 DVB-T (SAA7146) Using my favorite card (the 1200) i tried a frequency search in MythTV using one of the mux frequencies and the other bits I knew. No luck :( Then I tried the same using the Nova T 500. Yes it found and locked to channels ! Anyway to cut a long story even longer ;) ... I read the resulting entries in the mythtv database and edited my channels.conf then tzap worked with both cards ?? scan was saying ... SVT1:650000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:1019:1018:1010 when MythTV and tzap needed ... SVT1:650000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:1019:1018:1010 ie. FEC_2_3 and GUARD_INTERVAL_1_8 were needed for tzap and MythTV using scan again with a few -vvv gave this ... parse_terrestrial_delivery_system_descriptor:498: 0x3184/0x3fd 650000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE ie. the wrong?? FEC and GUARD interval Anybody know whats going on here ?? Is the network sending wrong info ??
