Strange problem with PVR 150MCE

[nigma]

Hey all, I have a MCE PAL version of the 150 board. The problem I am having is weird.

I can set the card up to look perfect, good balance of blur and sharp with the dot crawl registry fix. Good colour brightness etc. with the Tweak tool, even saving on a restart. The problem is after having the card playing LiveTV for a while it gradually changes the colour settings, its like it goes dark and high contrast, looks terrible. To fix it I have to play a recorded tv show then go back to LiveTV and its back to default settings, or restart fixes it too, but then again within about 10mins the picture goes bad, its like its automatically adjusting the picture depending on what it sees.

This is all in Windows Media Center, anyone else seen this issue? It basically makes the card useless for recording. =(

Do the values in the proc amp change when this is happening?

no they don't, it seems to be happening besides those settings, like underneath them at a lower level.
