Not sure I expect a solution, but its quite annoying how long it takes to cache my media library on my iPad 4 compared to using my ATV 3. It takes about 3 seconds to connect and populate my iTunes media library on the ATV, vs about 1-2 minutes each time I open the "Video" app on the iPad. This has to be recached if the app closes for a period of time. Both are connected via wifi accessing content from the same Win 8 PC running the latest version of iTunes 10. Is it too unreasonable for me to expect apple to make home sharing work as well on an iPad as it does on an ATV?
