I have this issue as well.  If video is coming off the Television input 
of my tuner card (ATI Wonder TV VE), the image is b&w.  However, if I 
select the Composite1 input (hitting "c" in mythtv), the signal comes in 
full color.

For testing I have an antenna hooked up to a VCR, then from the VCR I 
have both coax and an RCA composite running to the tuner card.  The 
signal over the coax seems to be interpreted as b&w, but the composite 
is color and looks just fine.

It behaves the same way in XawTV, so it's not a MythTV issue, but 
probably a card driver issue.
