I've gotta get screencaps for Xtras (which I keep procrastinating on) so I'll see what I can do about that shortly.
As for the 720p encodes for 1 and 2, HACK-JOB's are undoubtedly better. 99% of the time, our 720p versions are just re-encodes of the 1080p encodes. They have never been a focus of mine, but enough people demanded them so we did them, and for better or for worse, re-encodes were the way we had to go. If I had more time and money, I could encode the 720p myself, but the lack of a system to encode them on and the need to encode 1080p stuff on my desktop kind of rules that out.
