I downloaded some videos that I wanted to put on my iPhone (Oredev talks, from http://vimeo.com/channels/oredev, so from the web and not iTunes). The videos are all seemingly in the right format, and they play using Quicktime and in iTunes. But when I select them for sync to my iPhone, only a few of the several I've tried have transferred successfully.
The most frustrating thing is that there's no information on why this isn't working. Is there some kind of log or other place I could look for errors or other messages on why the item didn't sync? I'm assuming it's just being very picky about the format, but I'd really like to get more insight before I just start blindly trying things.
UPDATE: I ran the videos through HandBrake, and, while it did seem to help, there's at least one video that still won't sync onto my iPhone. It's checked for sync in iTunes, and iTunes doesn't tell me anything went wrong. There must be some kind of log I can check to see why the item didn't sync, right?
