I would like to add my own voice to Michael's complaints. I think I should refer to iPod Touch "peculiarities".
1. My podcasts in iTunes will progress from the newest to the oldest(bottom to top). In my iPod Touch, the podcasts are played from the oldest to the newest(top to bottom).
2. On the iPod Touch, I can play all the available podcasts within a given subscription but in iTunes (on my iMac) the progression is from the newest to the oldest within a given prescription and then it keeps going into the next subscription and again plays from the newest to the oldest.
3. Like Michael, not all of my podcasts subscription are synched over from iTunes on the iMac to the iPod Touch. But then, some of them are. I've stared at the settings until I'm blue in the face and have not been able to get the same synching performance from the few as I can get from most of the subscripions.
4. I cannot figure out why Apple makes a distinction between a movie and a video podcast. Is it so that one can subscribe to a video podcast but you have to download movies separately one by one?
5. Sometimes I can delete a podcast on the iPod Touch after I've listened to it or decided not to listen to it at all and other times the delete function does not work. A work around seems to be to completely turn off the iPod Touch and then start it up again. Is the operating system that fragile on the mobile devices?
Fortunately for you all I've run out of steam for tonight but I may continue this list another day.
