Rented the Dark Knight Begins on Amazon Prime last night. Plugged my PB directly into the TV via DVI. Worked beautifully. Sound and picture were awesome.
I did noticed that when I bridged from my 9900 to PB (so I could pause using the remote control) things started to hiccup. So I had to go to the bridge options and switch off all the synching features (email, browsing etc) and everything was beautiful after that.
Loved it!
