Re: Nova-T 500 issues - losing one tuner

Hi People,

I am writing to inform you of a simple tool I have written to help with this 
tuner issue. The tool I have made will monitor dmesg output and reset the 
MythTV Backend if it detects a mt2060 errors. It is not a fix, but a 
workaround. 

I have written it for Ubuntu/Debian based systems. I have included the GPL 
source, feel free to modify as needed.

I have it installed on a friend and my Ubuntu based boxes for the last few 
months and all seems OK.

To help with debugging issues, a log is written to:
/var/log/mythwatch.log

Example output:
[24-2-08 19:51:34] --- Started Ver: 0.2.3 ---
[27-2-08 07:33:52] ERROR: Disconnect Detected.
[27-2-08 07:33:52] ACTION: Attempting mythtv-backend restart.
[28-2-08 05:47:20] ERROR: Disconnect Detected.
[28-2-08 05:47:20] ACTION: Attempting mythtv-backend restart.
[28-2-08 16:51:28] ERROR: Disconnect Detected.
[28-2-08 16:51:28] ACTION: Attempting mythtv-backend restart.

Note: It is not perfect in that sometimes I loose a tuner without a mt2060 
error (very seldom). I am working on the idea of scanning for PAT errors in 
the MythTV backend log. There seems to be a connection with loosing a tuner 
and PAT errors.

The tool allows you to record your shows at almost 100% reliability, but with 
the chance that a reset could lose a few seconds of a recording. This will 
happen if a reset happends while a show is being recorded.

Cheers
Shaun
