My problem is that I can't stream movies via Airplay on certain websites. For example: I can play videos from a site (rainiertamayo.com) on my computer but as soon as I switch on mirroring via the Apple tv, the stream freezes and won't play anymore. It had been working just fine for a few months, but stopped all of the sudden. I've got a MacbookPro from 2011, a brand new 3rd gen Appletv and a Sony Bravia tv. All the apps work/stream great. I'm able to use Airplay to mirror my screen to surf the web, use other websites to stream videos but this one won't work. Does the site or Apple have some sort of restriction on this?
