[mythtv-users] Myth cannot find tuner after reboot

[Ian Hodgson]

I have been using MythTV 0.20.20070821 on Ubuntu v7.04 for the last 6 
months without any problems. Last weekend, I shut my machine down in 
preparation for a weekend decorating session.

Decorating done, I switched the machine back on this evening only to 
find that Myth cannot find the TV card. I have tried the various tests 
that I used when setting up the machine and have verified that the card 
is working. I started the MythTV back end set-up program and noticed 
that there were no Capture Cards listed. I reinstalled my card, but 
without success; MythTV no longer stores the card data that I add. A 
little Googleification points to a corrupted database and a reinstall as 
the solution.

This may be a good time to update to 0.21, but I have some questions 
about maintaining the data in my current configuration. Whilst the 
recording schedules are not so important, I would like to keep the 
recorded programs after the update so finally to the question; what do I 
need to do to fix my database and install the updated release whilst 
still being able to access my existing MythTV recorded files.

I should add that I am not experienced with mySQL so I would appreciate 
a pretty detailed rely.

Many thanks in advance.
