I think you might have to re-encode the theora video, so that you get
one single continuous stream with one set of stream headers.
Theora-in-matroska doesn't really support jumping onto another stream in
the middle of the file.

ges-launch / gst-editing-services might be able to help with the big
picture stuff (but for ges you'll need git / latest 1.1.x if you're
using 1.x [which you should use]).
