I have an interesting problem with MediaPortal, that I've observed in the earlier 1.x.x beta builds, and is also there in the 1.1.0 RC1.

The problem: I get a .net exception when attempting to start the client interface if the system has woken up of it's own accord.

I have my system set to go into standby after 10 minutes of inactivity. The system wakes up, records shows and goes back to sleep without a problem.

I can wake the system up (wiggle mouse or press power button), use it, and let it go back to sleep without a problem.

If, however, the system has woken itself up for some purpose, e.g. EPG update or show record, then it seems that MediaPortal only initialises the TV server, it does not initiate the client interface. To wake up the client, I need to wiggle the mouse or send an IR power command to get it to initialise the client.

When the screen appears after wiggling the mouse to initiate the client (warm-up on my plasma is ~10 seconds) all I see is a .net exception dialogue. If I click OK to this exception dialogue, the MediaPortal client user interface then loads and appears to work as normal.

I'd love help to solve this problem. Having to click OK to this .net exception dialogue is getting me out of the couch way too often.

Edit: I also use MST because the Dell doesn't go into standby when it should. This is a PC dedicated for media centre duties, so everything on the system serves that purpose.

Bump. Anyone?

So MP is left running when you go into standby, try enabling the setting under general to restart MP on resume (Nvidia fix).

from error.bak.

 

[Newman]

Thanks for that.

I'm using a generic Nvidia GeForce 8400GS with pretty recent Nvidia drivers, so I don't quite understand why my device offers reduced functionality. After clicking OK to the exception, MediaPortal seems to work just fine.

MediaPortal was already configured to restart on resume as I could never to get the MediaPortal interface to work on resume otherwise. I've just enabled the option to apply the workaround to prevent MediaPortal freezing on resume on some systems and will let you know.

ps. the new nvidia drivers suck, both my gt220 and 6600gt rigs BSOD with anything after 190.45 and a lot of people are having issues post 186 drivers according to their forums.

 

[Newman]

Hmm, I still have the issue.

Thanks for the tip about the Nvidia drivers. I'm on 196.21. Will try going back to an older version and report back.

 

[Newman]

Hmm, nup. I still experience this error on Nvidia drivers 186.18.

Any further help or tips on where to look next greatly appreciated.

I've just done a completely fresh install using 1.1 RC2, after doing a full uninstall of RC1. I am still getting a .net exception when the PC wakes up and starts MP. Any further help would be appreciated.

I've tried nVidia drivers 186.18 and 196.21 as well as the ones from the Windows Update site. I've tried re-installing all the .net redistributables. I've tried just about every possible combination of options on the general MediaPortal configuration panel. I've updated my CODEC pack to K-Lite 5.9.4. I've tried making MP delay for 20s on start-up just in case the exception occurs due to something being initialised... I'm stumped.
