I've got a bit of a strange problem that's apparent in both MP 1.0.2 and the 1.1.0 Beta. When switching from TV into video playback (can be a DVD or video file) without stopping first, I get a blank white screen (750x600 pixels) that covers everything but the some of the sides on a 800x600 pixel display, almost like a big piece of paper. The videos and DVDs play fine, and otherwise work perfectly. The white screen disappears if I switch on video wallpaper in the home menu, but comes back as soon as I focus back on the video. This problem persists even when all playback is stopped (with 'b') then started. Only a reboot fixes it up. The TV works fine all the time however. This has been driving the family nuts and is making the MediaPortal PC lose out over the set-top DVD player

That's exactly the issue! It only happens when teletext subtitles are enabled at the time. I can't use DVB subtitles for some reason even though Australia broadcasts them so I use teletext as a workaround.
Logs attached now.
