No. If you have to have the extra minute and you only have two tuners,
you need a third tuner to get shows A, B, and C.
You could use the global pre-/post-roll (which is meant to give your
cards time to start up/for STB OSD's to disappear/etc.) to say, "if you
aren't already recording something in the previous timeslot, record an
extra minute". Assuming you set a 60-second pre-roll and a 60-second
post-roll, with:
Show A: 8:00-8:30 on channel 1
Show B: 8:30-9:00 on channel 1
Show C: 8:00-8:30 on channel 2
you would get recordings that are something like
7:59-8:30 on channel 1 (show A)
7:59-8:31 on channel 2 (show C)
8:30-9:01 on channel 1 (show B)
or
7:59-8:31 on channel 1 (show A)
7:59-8:30 on channel 2 (show C)
8:30-9:01 on channel 1 (show B)
depending on priorities (and note that you may still have two tuners
recording on channel 1 for a minute).
And, if you're not recording show C, you'd get:
7:59-8:30 on channel 1 (show A)
8:30-9:01 on channel 1 (show B)
in other words, it won't start up the second tuner just to give you the
extra pre-/post-roll.
