My understanding (and I may be out-of-date so please correct me if I'm
wrong) is that soft padding is applied after the schedule is determined.
This means that if you use soft padding and have two tuners capable of
recording the two adjacent shows then the padding will not be applied and
the shows will both be recorded on the same tuner. This is less than ideal,
particularly for people who have say analogue Sky on one tuner and then DVB
multirec on another - the soft padding will be lost on shows on Freeview
unnecessarily.

If Mythbusters is the only case where this issue is coming up frequently,
just let it record another showing: both the current season and the earlier
season repeats are shown multiple times per week.

It'd be great if the scheduler were able to handle padding better.
Unfortunately it's not as simple as it first seems and the scheduler itself
is a complicated piece of code. That's why multirec is implemented the way
it is - having "virtual tuners" may be a bit of a hack (with its unnecessary
requirement of pre-determining how many you might need), but it meant it
could be implemented without a lot of changes to the scheduler. I believe
there's been one aborted attempt to get the scheduler handling padding
better, so I suspect it'll be a while before anyone tries again.

Cheers,
Steve
