I was referring to the software encoders that I either use personally or
have recommended/reviewed.  And you are correct, those are on Windows.

I'm glad to hear that at least the most computationally demanding task
that a user is likely to perform is done concurrently on Macs, and I
hope that more applications, on both Macs and PCs, do so soon.

Actually, the situation with most PC encoders is even worst than I
suggested--many of them will insist on transcoding a huge video file
even when it is already in the proper format--change a frame, re-encode
a whole file!
