When you saw it showing the wrong day, was that in the DVB stream or your old 
digital tuner?
Reason I ask is because I suspect the software in the dedicated tuners is, 
ahem, less than optimal. For example in the past I had the EPG information 
displaying about 15 minutes delayed. Turning the unit off and on fixed the 
problem... hence I assumed the internal clock was dodgy and needed resetting.

I'll experiment and see how accurate it is... I was thinking of augmenting the 
scheduler so that if it sees a program to be recorded as the next program in 
the EPG it waits until it flips to current before recording. If it doesn't 
see it then it just records manually as now.
(well I'll printf messages for now anyway!)

Yes the terrestrial TV channels put out PDC signalling information in the 
teletext block, which can then be picked up by PDC video recorders.
Allegedly a couple of UK Freeview channels still transmitting the old PDC 
signals, although, that is just anecdotal off some website so I don't know.
