Whatever changes Apple has been making to the iTunes Store back end lately has caused iTunes app on the iPhone, iPod touch and iPad to stream some podcasts as music samples, rather than handing them off to the built-in media player like they're supposed to.
We've tested and everything seems fine and working properly for all of our TiPb podcasts like iPhone Live or iPad Live, or ZENandTECH, Superfunctional, or Iterate, or any of the Mobile Nations podcasts for that matter.
However, shows on other networks like 5by5 and TWiT do seem to be experiencing the problem, and it's annoying to say the least. So what can be done?
