I just recently have been having issues with my iTunes podcasts. Once I sync my media to my Tour some podcasts which are all music files come up as videos and now they have been crashing/rebooting my phone...
i just downloaded some podcasts on my tour..i transferred the podcasts using a card reader...and then put them in the podcast folder..i usually sync my media using the DM but it seems that using the card reader..is alot faster..
don't know if this helps you...just telling you what i did
