Huh? Transformers: Revenge of the Fallen runs between 35-40 Mbps for
most of the movie, and as I said, once it gets to chapter 4 and starts
multithreaded decoding, it plays back perfectly fine. CPU is typically
65-85% busy on each core, and that's will an older Core 2 Duo (E6750
2.6 GHz). My Core i7 920 (2.6 Ghz) can almost play back on a single
core with software decoding (some part work fine, but some are
choppy). With an i7-960 (3.2 GHz) smooth single core MIGHT be possible
(or might not....if anyone owns one, I'd love to hear)

Yeah, but I'm still on 0.21 at the moment, and an upgrade would not be
trivial (I have 4 myth systems, and a lot of customizations).
Transcoding is a lot less painful at the moment.
