I dont think there would be any video out there are formatted with .x264
With all the complaints about no DivX support, I was wondering if there was something out there.
A few sites list x264 files for TV episodes, especially for popular shows like Lost. They are x264, 720p ".mkv" files. They are either 700MB or more often 1GB, instead of what looks like a standard 350MB
I assume that these are the closest thing to AppleTV format as you are likely to find (but maybe they aren't 24fps?). Given that the handbrake forums say that their x264 works for AppleTV, maybe it's all fine.
Anyway, would the .mkv container format be recognised by iTunes? Is there a way to simply switch the container to .mov without re-encoding the h264?
