[mythtv-users] Picture in picture not working....?

[Andrew Wilson]

I've got dual DVB-T tuners in a VIA M10k with debian 2.6.9 and
unichrome drivers. Myth is going nicely, but for a few problems.

I can't get picture in picture going at all. V is supposed to toggle
it on/off, right? Doesn't do anything for me. Each tuner works fine. I
can record off both simultaneously, and the Y key to change inputs
works.

Has anyone got this feature working?
