I am having a similar problem with my 30gb ipod vid. I can play my movies in itunes (downloaded and added to itunes library in mp4 format) but when I transfer them, I cant watch them. THere is that infamous blank screen and then it goes back to the last menu. Also, i noticed a while back I had this problem with my photo's. I could view the thumbs on my ipod. BUt when I started a slide show, the same blank screen came up and returned to the menu. I am also noticing that it did the same for 4 out of 10 MP3 files that were part of an Anne Frank audiobook. Why would 4 of these files play and 6 refuse to do so. *note: there seems to be a small exclaimation point on the left of the file name. (not in the itunes library, but under my ipods library. PS> I apologize for the lenght, but I hoped someone here would see this and recognize one detail and help. Thats what were here for anyway, right?
