Not sure if I read right, but are you connecting the cable (f connector) and the S-video to your PVR-150. They are the same input. I ran into this back on my Win32 machine. I ended up ordering the daughter inputs for the card but it still did not work with WinMCE, It did give me the 2nd input however I could not access it in windows unless I used the Win2000 software supplied with the non MCE pvr-150.
You may though with Lmce be able to setup the daughter input board in Lmce as a 2nd input which it enables automatically on the card and then switch via media scenario's.
Yes, that's correct, s-video and tv tuner on the same card, and part of the question. The reason for this is using the TV card gives me a second tuner (in addition to the set top box), however it's only a subset of all the channels available which is why I also want to use the s-video input at times 'cause it will allow me to record every station the STB gets.
s-video - every channel but can only be used alone as it uses the STB and the PVR-150
fire-wire - only chanel 2-99, best picture quality, doesn't use use the PVR-150, uses STB
tuner - only channels 2-99, uses the PVR-150, doesn't use the STB
