[mythtv-users] mythtv (or driver) hangs my mythbuntu box

[José Silva]

I hadn't experienced this since I switched from Windows, I mean, having 
to reach for the BRS (big red switch); not once since I am with linux.

After years wrestling with sound with a Pinnacle PCTV USB tuner, see:

  [mythtv-users] No sound after channel change with Pinnacle PCTV USB2 tuner

I decided to buy a MPEG2 hardware encoding tuner as someone advised, in 
the instance, an used WinTV-PVR-USB2. I tested it with mplayer and it 
works ok.

So, as I am already used to, I installed, uninstalled, reinstalled, 
reformatted, clean-installed... mythtv (and mythbuntu) many times. And 
after many unexplained bump-outs and hangs, I reached this totally 
reproducible situation:

On a clean installed mythbuntu with a WinTV-PVR-USB2, when I click 
WatchLiveTV the system completely hangs; no doubt, even ssh hangs. This 
happens either accessing with the frontend of the backend server or 
using a separated frontend machine.

After PowerOff/PowerOn and looking at the extensive log:

Query was:
SELECT r.title, ...
...
Bindings were:
:CHANID=1135, :RECSTARTTS=2011-12-07T18:36:45
Driver error was [2/126]:
QMYSQL3: Unable to execute statement
Database error was:
Incorrect key file for table './mythconverg/recordedprogram.MYI'; try to 
repair it

2011-12-07 18:39:32.061 
RingBuf(/var/lib/mythtv/livetv/1135_20111207183645.mpg) Error: 
OpenFile(): File too small (0B).
2011-12-07 18:39:32.155 DB Error (LoadProgramFromRecorded):
...

I have to say that before this, I had repaired the database using 
mythweb and deleted all files from /var/lib/mythtv/livetv. So, I suppose 
the error on the key file happens during the process, everytime.

So, can anyone point me a direction, please?
