Podcasts in both iPhone and iPad will play for a minute and then reset back to the beginning, can only stream, cannot download - no problem on PC laptop with exact same Podcasts with exact same internet set up. What is the fix?

This is incredibly frustrating - we had a IPhone 4s that had no problems here for about 7 monts. We have a new IPhone 4s and recently a new IPad 2. Ever since the mandatory switch to using the Podcasts App for iOS based products (my PC laptop works fine), the podcasts will say "cannot be downloaded at this time" and will stream for 30 seconds to a few minutes, then abruptly start over at the beginning. We cannot fast forward ahead properly in the new clunky interface, and the secondary screen where you get to see the "tape player" going through podcast does not skip when you move the timer icon anywhere in the podcast. It is though they are running in parallel.

We are talking podcasts by the BBC, NPR, etc and the Lenovo doesn't have any issues bc the whole system is inside ITunes.

I have looked all over the internet and cannot find a fix, please help.
