Although you're getting slightly different symptoms, perhaps let's give the following user tip a try. (I haven't got the precise symptom set fully nailed down yet.)
Hi b noir,
No, sorry, that didn't work
When I click play it just freezes, right then and there. It doesn't give any indication that anything is loading, or anything. Here is an example of what I see: http://screencast.com/t/j2IEzzKh
As you can see audio plays fine, but not video. The same thing happens with video podcasts and even with movie trailers. This Movie in my library plays fine on my other computers and iPhone as well.
Doublechecking. When you uninstalled iTunes, was it a complete uninstall/reinstall, as per the following document?
(Checking, because I think some of the video-playing-componentry is kept down in Apple Application Support nowadays ... if there's an issue with that stuff, just uninstalling and reinstalling iTunes on its own might not clear away the trouble.)
I started having the same problem several days ago possibly after installing the latest iTunes update. The problem is still not resolved completely, but I manage to get my videos playing. So here is what worked for me: I started iTunes in safe mode (which disables any third-party plug-ins, detailed how-to is here: http://support.apple.com/kb/TS3430 ) and tried to watch a random trailer in Apple store, it worked. Then I tried to start a rented movie and iTunes crashed. I started it over in safe mode again and watched the whole movie without a problem. However, the video still doesn't run if I start iTunes normally, so we need a solution for this. Well, better than nothing
I had this same problem s a lot of others after updating to the latest I Tunes version. I finally got a decent response back from Apple, which was hard to do. Here is what they told me. Maybe it will help you:
