Re: [linux-dvb] Nova-T 500 issues - losing one tuner
When I was having the problem, I was running 2.6.22 (vanilla ubuntu), so it doesn't appear to be related to kernel version. The fix posted a few weeks ago does seem to have stopped it for me. I said I lost a tuner recently, but I think that may have just been a loss in reception.

Re: [linux-dvb] Nova-T 500 issues - losing one tuner
I am quite disappointed to report that one of my tuners has just died
this evening. No error messages to speak of.

Which one disables the remote? I don't use the remote, so I could try disabling it and see if I get any problems.

Re: [linux-dvb] Nova-T 500 issues - losing one tuner
I'm running a 2.66ghz Pentium D. I don't use the remote. It seems to be pretty sporadic - it's been working for a couple of days now.

[linux-dvb] Nova-T 500 issues
I am using the (almost) latest SVN version of mythtv. I am using the v4l-dvb sources from a couple of days back. I have followed and used the patches that were on (are they in the repos now?): http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500 After a short while, one of the tuners dies. I get a "(L__) Partial Lock" message from mythtv. If it's any help, I also get messages like: DVB: frontend 0 frequency limits undefined - fix the driver In syslog, but that's even when it's working fine.
