I can confirm that under windows the WinTV Radio program does stereo
and even autodetects which stations broadcast stereo vs mono (not
everybody broadcasts stereo here). Unfortunately I cannot test that under
linux since my test system does not have any speakers and I 'm testing
with a *single* headphone (the one attached to a close-talk mic). So no
chance of testing whether it sounds like stereo. (Otherwise I would probably 
have caught this earlier). This is for a model 29034.

So, it is either a bug in the demodulator, or we are missing some bit
of (initialization?) code or doing something different. In any case, this 
needs more investigation.
