I agree this might be a problem with PSIP *support.*

Back when I was still trusting my local PBS stations to
keep my DVDR clock accurate, the DVDR managed this quite
nicely with a single tuner.

PSIP could be done the same way. Update when the TV and
recording devices are off.

A second tuner might be okay too, especially once prices
have had a chance to drop. Seems rather brute force to
me, though.
