OK, this is a <really> wierd one.

Over the past few nights, I've been watching an episode or two of the Simpsons before going to bed. After I finish watching, I quit video player and then just replace the cover (not switched off) on the IT and put it away.
Next morning, I pick it up, take the cover off, nothing. Totally dead.
I hold the power button down, it's still totally dead.
The only thing I can do to get it to work is to remove the battery for a minute or so, put it back and switch it on. It then comes back to life as though nothing has ever happened.

This has happened 3 days in a row and only happens when I use the video player. If I do anything else before I put it to sleep, it's fine.

Has anyone else noticed this outrageous behaviour. Is it Simpsons related?

Does anyone have any ideas - right now, I'll listen to anything, honestly!
