Cannot copy certain podcast episodes to iPhone My iPhone (3GS, 5.1.1) has decided that certain new podcast episodes simply cannot be copied to the phone. When I move them from the iTunes Podcasts category in the library to the phone, nothing happens. This applies only to the newest one or two episodes of each affected podcast. Other episodes copy nicely.

I tried deleting all podcast episodes on the phone, rebooting the phone and restarting iTunes.

Any ideas?
Some podcasts are video and if the resolution is too high for your device, it will not work.
