FWIW, in 0.22 and above, both mythtranscode --buildindex and 
mythcommflag --rebuild should work the same on all videos.

The problem with the MKV is (to quote someone much smarter than I): 
"seek tables for mkv should generally work. they don't work for h264 in 
mkv since we can't parse the bitstream format mkv/mov/mp4 use to store 
h264" (meaning that we create an empty seek table for the video, which 
is A Bad Thing (TM)).
