Everything was fine yesterday. I think there were a couple of XP updates, so I don't know if they're related to this problem. I updated MovingPictures to the latest version as well, but I doubt that's connected.

After a cold boot, selecting any channel in the EPG just results in an error or MP locking up. If I try and stop the TVService from services.msc, it doesn't work and says it was unable to complete and the service is left in "Stopping" state. There's a lot of errors in tvserver_error.log

This appears to be an old hard to track down bug

2011-03-13 19:24:52.578125 [(6)]: Exception   :System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Searching for "System.AccessViolationException: Attempted to read or write protected memory" brings up some threads from a few years ago but they suggest idle EPG grabber or the DVB Fix not being applied (perhaps a recent Windows update un-did it???)

Is this problem re-producable ?

Also probably worth just checking the database. Open up a command prompt
navigate to MySQL Bin folder (is C:\\Program Files\\MySQL\\MySQL Server 5.1\\bin for me) and enter

mysqlcheck --user=root --pass=MediaPortal --auto-repair MPTVDB

Thanks for the tips.

Unfortunately, this problem is very much re-producable. Every boot I have the same problems. I've installed MP1.2 on a separate partition for now, so I can at least watch TV but obviously a lot of plugins aren't compatible with that yet, so it would be nice if I could get this working again as well.

I've tried running the dvbfix again, but that hasn't helped.

I was using the loopback adapter technique, but I've disabled this now and changed all the settings to point to the PC's actual IP address, with no change.

The first run of the command given was as below. Subsequent runs show all OK

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqlcheck --user=root --pass=MediaP

Just to report I've done an uninstall/re-install of 1.1.2 and it's OK again
