MythTV as a whole is licensed under GPL version 2. This is unlikely to
change. If it were it would most be to change to GPL version 3 or a

IANAL but if the resulting work could be considered a derivative of
MythTV (i.e. it's still a DVR) I don't think any level of indirection
would provide legal cover. I recommend that you study MythTV but
in the end write your own PVR software. This will also allow you
to avoid some of the design mistakes we made that have been difficult
to back out of. Many base libraries we use, like ffmpeg, are available
under either an LGPL license or another license that allows integration
with proprietary code.
We made the conscious decision to license MythTV under the GPL, one
of the reasons was so our work on the project could not be used for
proprietary software that would compete with an employers' software
or with MythTV itself for that matter.
