If HVR1300 (analog part) its added as card 1 & PVR150 as card 2, the picture with PVR150 its to dark when viewing in MP.
If the HVR1300 its added as card 2, it is too bright when viewing in MP. So MP seems to adapts it's settings from card 1

Reproduce:
Two cards (HVR1300 card 1 & PVR150 as card 2)
Open Fullscreen TV & start recording -> change channel so the next card is used. The channel (on PVR150) its now to dark.
