I am using the stuff on Windows and both iPodder and Doppler works fine.
No problems. Are you sure you are pointing the apps to the right location?
Have you used RSS viewers before?
As for shows - I haven't found any really good music shows (yet) - I'd rather
listen to pirate or the Beeb/XfM:
a) most of these guys are talking about the technology itself or technology
b) musical content: two schools: post illegal content (or very close to it) to raise
your own profile or post legally (using ie CC-licencesed stuff).
c) some of the americans are just over the top with excitement ... and then play pap
(probably the american dj style - what do I know).

Since I haven't found anything I like yet I intend to do my own thing.
diy/punk style -
prepare for some more pap: I've got an awful voice (I am trying to find Thatcher's voice coach as we speak. haha) and my taste in music is horrible (as already proved in other sub-fora).
