Solved this - recording below for future reference:

Turned out to be two problems:
1)  The only filetypes allowed for direct download in Mythweb 0.22 are
.mpg, .mpeg, .mpeg2, and .nuv .
To allow for mkv (and others) to be directly downloaded, edit
/usr/share/mythtv/mythweb/modules/stream/stream_raw.pl and add the
filetype under "# File Type" (line 26).

For example, mkv files can be added under the .nuv section with the following:

 elsif ($basename =~ /\.mkv$/) {
         $type   = 'video/x-matroska';
         $suffix = '.mkv';
     }


2) I had characters in my filenames that did not get parsed correctly
by Mythweb, and hence never got converted to flv for streaming. After
removing all ampersands, commas, apostrophes, and parenthesis,
streaming worked on all files.

Hope this helps someone in the future.
