Actually I didn't. The problem I see is just how to code this into myth. 
What if we have a card listening for the vps, but then a user starts 
watching livetv on another channel? or when I have 3 recordings 
scheduled on one day, each on a different channel. One at 16:00, one at 
18:00 and one at 20:00..   I would need 3 cards in order to detect the 

All those worries aside, I think the suggestion mentioned previously 
isn't a bad one at all: Since programs usually get scheduled later 
instead of earlier, just start recording say 10 minutes before the 
program is supposed to start, and when you receive the vps, set a marker 
there (or cut it already right there, not sure if thats possible).

I think I can easily live with not supporting vps when a program moves 
to an earlier time.

Another concern would be on what to do if the program gets moved an hour 
back, and because of that now conflicts with another (possible also 
vps'd) recording.

Ugh.. brain hurts :p
