MP stops responding when watching TV (1 Viewer)

[MPM]

Few weeks ago I started using DVBSBridge as my main TV source and have since then had some annoying issues with TV watching... Every now and then I lose control of MP. At first it seemed like the remote didn't work at all, but then I realized that only commands that still worked were rewinding and fast forwarding, i.e. navigating within the time-shift buffer with left and right arrow. All other commands and remote buttons are completely ignored and nothing is displayed in the GUI. Only way out is restarting MP...

I have verified that this only happens when using DVBSBridge as TV source, but DVBSBridge itself seems to be working fine when this happens so I'm trying to understand where the week link is.

I can see from the log files that something's wrong but don't understand what or how to approach it... I've attached log files that seem to reveal something interesting, other log files look fairly normal to me.

Any hints?

Regards,

Log from DVBSBridge probably doesn't reveal anything interesting even if it mentions an error. Following two lines are repeated all the time, regardless if I have issues or not:

11/05/09 20:44:59   CDBoxSourceControl::ProcessTransportStream. Error. Transport stream packet does not start with 0x47
11/05/09 20:44:59   Error. CDBoxStreamHandler::StreamingThread. No 0x47 at the start of received data buffer

MP's error.log displays following message when MP stops responding:

2009-11-05 18:26:31.259926 [ERROR][26]: render exception:System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

And MP's main log looks like this:

Did display drivers crash or was the HDMI / DVI connection to the monitor / tv closed? DirectX reports device lost in such cases.

 

[MPM]

My guess would be neither...

When this happens I can continue watching TV so I assume that both display drivers and HDMI connection are still in order. The only symptom I get is that MP stops responding to all remote input except for left and right arrows.

Looking at the error.log info, the first error (18:26:31.259926 [ERROR][26]: render exception) is what happens when the described issue occurs. The second error (20:43:54.025551 [ERROR][MPMain]: Main: Device lost) is what happens when the issue has already occurred but I continue trying to "regain" control by pressing remote buttons much harder...

Does the issue happen also with the default skin?

 

[MPM]

Yes. I was suspicious about the skin as well, that's why I didn't post before... The included logs are taken when using Blue Wide.

It may also be interesting to know that this happens every time when I try to watch TV while it's recording and only occasionally without recording.
