Me too...
iPad 2 update to iOS 6, and it doesn't seem to work anymore. Works fine between my iMac and wife's MBP. But on my iPad, when I try to connect under Videos, the little "time" icon (or whatever you call it) gets halfway and just stops there. For Music, it just loads and loads (or acts like it), but then never loads. Seems to be an issue with iOS 6?
