Yes, if you encode it as MPEG, e.g. as an I-frame.

Sending uncompressed pictures to OSD is also supported but not very
usable do to the small OSD memory (max. 4 colors at full resolution).
One could write a picture directly to the frame buffer of the MPEG decoder but
this is not supported right now and transmitting uncompressed pictures
to the card would be rather slow.

Not really a priority right now.
Data sheets for the tuner, video decoder and MSP chip are all freely
available though.

Yes, but even if the addon board were supported you couldn't capture
analog cable TV as MPEG2, unless you pipe it through an MPEG2 encoder 
afterwards of course.
