Hi all. I have 2 Leadtek DTV2000DS PCI tuners in my mythtv pc. This is a AF9015 + AF9013 + NXP TDA18211 based PCI card. The tuner is detected as TDA18271. (see http://linuxtv.org/wiki/index.php/DVB-T_PCI_Cards#Leadtek) My issue is that I can't lock onto any channel. My PC is: MB: Asus M4A87TD-USB3 AM3 CPU: AMD Athlon II X2 250 3 GHz RAM: Kingston 2 Gb single PC10666 (1333 MHz) PSU: Zalman ZM500-HP 500 W Storage: 2x WD 1Tb Caviar Blue 7200 RPM SATAII OS disc: Kingston 64 Gb SSD SNV425-S2 GPU: 512Mb Winfast NVidia 8400GS Remote: Hauppauge MCE remote I am running Mythbuntu 10.04, updated to the 2.6.32-26-generic kernel. MythTV is currently at version 0.24. w_scan shows that channels exist, but cannot lock on to them. It fails with either "no signal" or " __tune_to_transponder:1733: ERROR: FE_READ_STATUS failed: 121 Remote I/O error" Scanning in Mythtv 0.24 shows a signal strength of ~65-70% and gives me approx. 28 channels (Melbourne, Australia), but I can't lock on to any to watch them. http://linuxtv.org/wiki/index.php/Leadtek_WinFast_DTV2000DS#Making_it_work_in_Ubuntu has some recent updates dealing with different sample freqs and i2c fixes. As far as I know, I've applied them all. The output of uname, dmesg and w_scan is given below. I've inspected the output of compiling the V4L drivers (http://linuxtv.org/hg/v4l-dvb/rev/abd3aac6644e) and I can't see any error messages. I did a make clean before compiling. Are there any suggestions on what I can do from here? Some other questions: * What does the " __tune_to_transponder:1733: ERROR: FE_READ_STATUS failed: 121 Remote I/O error" error mean? * Are there any suggestions on cleaning before making? ie, how to do it? I just ran "$make clean" * Any other logs to inspect? (I've seen /var/log/messages and syslog mentioned elsewhere) * Blow everything away and start again? (I'm 95% sure I still have the V4L drivers I originally downloaded in late September, when I put this together) ( I don't really want to have to do this, but will if I have to...) * Try a newer kernel? dmesg does warn that the driver has been backported to an older kernel. Thanks Matthew ****************************************************** $uname -a Linux matthew-desktop 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 09:00:03 UTC 2010 i686 GNU/Linux ****************************************************** $dmesg (after a cold start; grepped for dvb, af901 and tda18271) [ 3.851105] WARNING: You're using an experimental version of the DVB stack.
