I'm not sure this would be the problem because I have the impression
that the pitch is not that far away, but I may be wrong.  I'm saying
this because recently I had this problem when recording some keyboard
over an accoustic bass track which was in tune.  I searched throught
the MIDI keyboard documentation just to confirm that everything was OK
with it, i.e. no transposition of any sort.  Then I stumbled on the Hz
settings which was different in the jack daemon and the ardour audio
workstation.  Anyways, the effect was that the keyboard was more than
half a tone over pitch, which I think is not the case with the video
and MythTV.  But then, I never played with speeded-up videos so unless
there's music, it could be that people are indeed talking more than
half a tone higher - I'll check it out.
