White box/screen (1 Viewer)

[MrMel]

On all clients (various hardware, but well above spec's, some even extreme gaming machines) when going from TV -> play a movie (AVI etc) if I dont stop the TV playing with "Stop", I get a white box infront of the movie covering "4:3" size of the screen (not whole video)

If I press "stop" on the TV before starting to view video all is fine.

Running Multi seat configuration

Logs are coming later today, when kids allows me to stop the playing...
Multi clients with same issue, all running different hardware

It feels like it started before I updated to 1.0.1, so perhaps a Microsoft Update/Change.

All clients are running Vista various versions.

Anyone have an idea or seen this before?

I was wrong, stopping TV does not always help.

Logs attached, anyone that see anything that causing it? (still on multiple clients, different hardware)
Very end of the log where it went white on me again. It seems that the size of the white box = native size of the video.

Anyone?
Ive played around with codecs but no go, restart of MP works as a "solution"

To answer my own problem, it only took 6 months and a few 100 restarts...

If teletext is enabled under TV, but not DVB-text, and you watch a TV channel with teletext subs, then try to play an AVI you get this problem.
Enabling DVB subs is enough for this issue to go away completly, so it seems that its something with the TeleText subs that's not cleared in the render engine..
