I would think it's very likely.  The various players probably look at 
different places in the recording to identify the streams that are present.

If you can create a series of cutpoints using the MythTV editor you may 
be able to get a usable version using this.  It needs only a seektable 
based on valid keyframes.  I haven't had occasion to use it recently and 
it used mythconfig.txt, which is no more.
