Well, if this was OK for DVD streams, it should be OK for PVR streams as well.
BTW the original commit adding "hint.software = true;":

commit d75a46a9f9626be12cc486c8e7c7d9be9d216922

    changed: only use libmpeg2 for dvd playback

    Side effect that vaapi/vdpau is now allowed for all mpeg2 content.

It would also be interesting to check an xbmc build using FFmpeg, it
may make a difference:
http://snapshot.debian.org/package/xbmc/2%3A13.2%2Bdfsg1-2~exp1/

I'm hesitant a bit, too to upload the change.
You may have hit a different manifestation of #769057.

Looking at the code it seems compiling with xrandr disabled may make
XBMC skip the OnLostDevice() call in CWinSystemX11::SetFullScreen()
possibly fixing both issues.
Could you please try disabling xrandr in debian/rules instead of using
the hint trick?

Cheers,
Balint
