Re: CH???, Bandwidth 8MHz, Fec_Hi 1/2, Modulation QAM64, Mode 8K, Guard 1/4, fails to tune\demux
Hi Barry, thanks for taking the time to reply (my previous more informative post was ignored). This is the Terrestrial transmission standard being rolled out across the UK, I live in one of the first areas to be upgraded to the new standard. Since the change, my DVB-T PCI card will no longer tune (despite the signal level being indicated as OK in Kaffeine). I have confirmed the card does work correctly under Windows XP with the original card software, so it does not appear to be a hardware issue. I have tried numerous apps and various kernels, all without success. Any guidance as to what to try next, be it how to gather info for a bug report, or even a solution :), would be greatly appreciated. -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi Barry, thanks again, I understood that reply. I got the Fec/Guard values I was using from the Windows XP app display, so am not surprised they are wrong :). Tried your suggestions, but no success. I have googled another user who has had success using a switched over transmitter similar to my local transmitter (http://www.dcglug.org.uk/archive/2009/09/msg00538.html), but is not using the same modules as me (saa7146, l64781). I have attached the tuning information from the Windows XP app in case you are interested. Not knowing what I am talking about - would the l64781 debug output help ? tvchannels.ods Description: application/vnd.oasis.opendocument.spreadsheet

Since the day my local transmitter 'upgraded' my budget DVB-T will no longer tune any station (tested with various apps, on various recent kernels), gut feeling is this may be a kernel driver issue. I know the transmission mode for all channels included changes from 2K, QAM16 to 8K, QAM64, and suspect this may be the reason (or one hell of a coincidence), can anyone offer any advice as what to do to obtain meaningful information to include in a bug report posting. PS. I tested the DVB-T card under WindowsXP and it (the hardware with the Windows software) works OK. I live in one of the first areas of the UK to 'upgrade'. lspci -v 02:09.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) Subsystem: Technotrend Systemtechnik GmbH Technotrend-Budget/Hauppauge WinTV-NOVA-T DVB card Flags: bus master, medium devsel, latency 32, IRQ 17 Memory at e3001000 (32-bit, non-prefetchable) [size=512] Kernel driver in use: budget dvb Kernel modules: budget -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
