AppleTV plays movie music, no vision. Hangs then crashes and restarts.

Question

I have a second generation AppleTV running software version 3.0.2.
I have had it for several months only just recently, when I play a movie that I have ripped using Handbrake the AppleTV plays sound but no picture, it then hangs (if I try to go back to the Menu) and then crashes before restarting.
I rip my DVDs using Handbrake with the following specs:
Format: H.264
Large file size selected
Average bit rate: 4000kbps
2 pass encoding
Frame rate: same as source
Aspect ratio: strict
So there is no reason why it shouldn't be playing video. Infact, I haven't changed my handbrake settings and have watched hundreds of video's previously with these settings, only just recently has my AppleTV been doing this.
Any suggestions?

Answer 1

For some reason, Handbrake, using the Apple TV 2 setting, changed the Output Picture Size from the 1280x720 of the original to 1276x734.  The Apple TV 2 would produce sound but no picture. 
Fiddling with Handbrake's Output Picture Size until it was "Anamorphic: 1280x720 Loose" allowed it to produce a playable file.
Handbrake often fiddles with the picture size but in previous encodings, not approaching the Apple TV 2's picture size limits, it hadn't mattered.
