I never used 0.25.
I'm running 0.25+fixes from git on lucid ..dvb-t freeview
I don't see any recording duration errors on TVNZ, my duration errors
were only on old recordings & fixed by mythcommflag --rebuild.
A/V sync is good.

Seeking back to beginning does cause 2-3 second hiccup..

Video playback is bad compared to 0.24+fixes, stuttering like cheap
digital handi-cam recording. 24p & i60 recordings seem to play okay (to
me).
This comparison was made by running 0.24+fixes & 0.25+fixes on the same
install/database etc.

I toyed with the idea of trying to reverse the, new to 0.25,p predictive
frame dropping/repeating/timing "feature" but can't understand how it
works.
