Let me come back on this again. I don't think I have tried the
scheduler on a programme mix quite like this, but does your system
normally start and stop recording at the listed change times with no
overlap allowed? I have front and back margins, so that around
changeover one channel needs two (virtual) tuners. Between 7:30 and
7:35 I would expect all four of your available cardids to be active, not
just the two that you seem to get. Another 'Schedule Option' to try?
Cheers,
