Hi ! Recently I have bought three TechnoTrend C-2300 for use in my Mythtv- system. Everything seemed to go smooth, but for a major share of the channels I have problems getting a channel lock. (Or if I do on some of them, I get a "distorted" image with lots of "bit errors".... Using the latest firmware for Linux : dvb-ttpci-01.fw-2622... After poking around the Internet I found that QAM 128 has been a problem for TechnoTrend cards, and the funny thing is that my cable- provider is using QAM 128 for all channels (including the ones that works very well). As I experience problems with most of my channels I still thought maybe this would be the problem. I haven't seen posts on the issue for quite a while and realizing that the latest firmware available for these cards is dated 2005, I wondered where I can find an updated version or if anyone has a solution to my problem........ Best regards, johan ---- $ lspci -vvv: 02:09.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) Subsystem: Technotrend Systemtechnik GmbH Octal/Technotrend DVB-C for iTV Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 64 (3750ns min, 9500ns max) Interrupt: pin A routed to IRQ 21 Region 0: Memory at feaffc00 (32-bit, non-prefetchable) [size=512] 02:0c.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) Subsystem: Technotrend Systemtechnik GmbH Octal/Technotrend DVB-C for iTV Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 64 (3750ns min, 9500ns max) Interrupt: pin A routed to IRQ 22 Region 0: Memory at feaff400 (32-bit, non-prefetchable) [size=512] 02:0d.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) Subsystem: Technotrend Systemtechnik GmbH Octal/Technotrend DVB-C for iTV Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 64 (3750ns min, 9500ns max) Interrupt: pin A routed to IRQ 21 Region 0: Memory at feaff000 (32-bit, non-prefetchable) [size=512] Syslog : Jul 9 19:18:48 xxxxxxx kernel: [ 53.409368] saa7146: register extension 'dvb'.
