[mythtv] Re: [PATCH] Soft padding proof of concept

[David Shirley]

Hi David,

I understand fully :)

i have created a patch - its probably totally wrong but it works for me :)

Basically it helps FindNextConflict pick a "the most recently un-used
used" card.

I have only done limited testing on it, and it seems to do what I
want, which is let me overrecord be used for as much as possible -
however i don't know what else it breaks - probably lots :)

Also the 600 seconds should probably be my overrecord amount but i
didn't know the variable this is stored in :)

Its like a hard buffer, but if the card is going to record the next
show on the same channel then it gets ignored :)

Also it will give you a conflict if you want to record on another
channel and don't have any other tuners - this is a bit weird but at
least the user (me) can see this conflict and decide on whether i want
to miss the end or start of a program.

Cheers
Dave
