Problems with video podcasts on 7th gen nano.

Video podcast episodes will either stop playing as soon as I try to start them, or they will play for less than a minute, then end abruptly, before the end of the podcast. The same podcasts play perfecly in iTunes, and also play perfectly in my 5th gen nano. I do have the 1.0.2 update, and this is my 2nd 7th gen nano (both had the problem).

Another issue is with podcasts with images, such as the Engadget Mobile podcast, which is supposed to display a picture of whatever device they are discussing for that segment of the podcast. In my 5th gen nano, the images are displayed throughout the podcast. In the 7th gen nano, nothing but the generic "i" symbol with the 2 semi-circles around it is displayed on the screen.
