Hi All, I purchased one of these recently; it has LR6550 written on the back of it. Here is what I know about it, cx2388 chipset, cx22702 remod, Thompson 7579 tuner - the card it self has RF IN + BYPASS, analogue IN + Svideo IN, + remote control. I have modded cx88-cards.c and some other files to add the PCI ID's and the card is detected. I can also receive a signal and capture picture using dvbstream | mplayer. HOWEVER the problem I have is tzap only gets 0x0031 (+/- 2) for the signal strength. Also the SNR is usually 0xffff when LOCKED. Also when I unplug the antenna or fake a bad signal (ie unplug it a little bit + wiggle) then the signal actually INCREASES to something like 0x0050 (always 0x00xx thou) Anyway this "low signal strength" causes Mythtv to ignore the card I think. Has anyone got any ideas/experience with this to help me out. Linux 2.6.14-rc3 if you are interested. Here is the tzap output using latest v4l-kernel + dvb-kernel cvs. tzap -c /usr/share/doc/dvb-utils/examples/channels.conf-dvbt-australia "Ten HD" using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 219500000 Hz video pid 0x0202, audio pid 0x0000 status 00 | signal 0030 | snr 8000 | ber 00003fff | unc 00000000 | status 1f | signal 0030 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0030 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 0030 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK As you can see from below, Michael Krufky has added this card into the cx88-cards.c in CVS.

I have added your patch into v4l-kernel cvs. "WinFast DTV1000-T" is now cx88 card #35. Please grab and install a copy of v4l-kernel cvs and confirm that it works properly. http://linuxtv.org/v4lwiki/index.php/How_to_build_from_CVS If you have any more patches to submit, please work from v4l-kernel cvs. About the bug that you are reporting about signal strength / snr etc..... The linuxdvb mailing list (subscriber-only: http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb) is more appropriate place to ask about it. It might be a good idea for you to try using the cx22702 frontend driver in dvb-kernel cvs before writing to that list. You can get combined cvs trees installed using most recent v4l cx88 driver + most recent dvb cx22702 driver by using the merge-trees make option, explained in the HOWTO above. Good Luck, Michael Krufky
