Sorry meant to attach.

Is this the error you're talking about:

Code:

Its something to do with the TV Guide, but its not clear what exactly. I've also not seen any other reports of this same problem in the past. Is there a set of steps to reproduce the problem? or did it just happen once?

[fletcher1717]

It has happened twice. It may be when I click ok on one particular channel.

The only thing that I can think of that could be causing this is I rebuilt this machine and copied the gbpvr.db3 file across from the previous build. Do you think that this could be causing the issue?

Possibly, the database files are not meant to be compatible between versions. This isnt the cause of your multidec problems though. This error is just about drawing the tv guide screen.

Both were version 1.2.13. I thought they would be ok. I will do further testing when the Mrs has finished watching Big Brother. I think that I may know what is going on here.

I will post back the results.

[fletcher1717]

Ok, managed to get the error again after a lot of channel hopping.

Looks like it may be to do with the drawing the signal meters.

Sub,
Can you have a look when you have the time, new logs attached?

[fletcher1717]

Hi Sub,

Did you get the chance to look at this?

[sub]

Yeah, but it was a different error to the earlier one. I'm not sure what the cause was.

[fletcher1717]

Is there anything that you can suggest to help me trace this problem?

[sub]

There seems to be two errors occuring in your logs. The first of these seems the most critical.

2008-08-05 00:09:55.468 ERROR [1] Unexpected error: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at FindFilterByName(Char* decoderName)

This appears to be an error occurring inside the mdapifilter when it tries to initialize. This could be caused by the mdapifilter, or maybe the multidec filters which are loaded.

Maybe the mdapifilter logs might give some insights.

It might be worth trying older versions of mdapifilter (with "reuse MDAPI Filter" setting enabled in the config app).

This seems to be a problem rendering either the TV Guide or the signal monitor. I've added some logic in the next release which should stop this occurring.
