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

Sat Oct 15 10:38:16 UTC 2005

ok that makes sense...

so i tried this:

#1 channel 7 is recording (card 1) something up until 2300
#2 i have scheduled something on channel 9 that starts at 2130 -> 2330
#3 i have scheduled something on channel 7 that starts at 2300 -> 0040

fine so far.

#4 now i schedule something on channel 9 that starts a 2330 -> 0130
and the #3 becomes red ie conflict.

i would have assumed that the scheduler would have picked card 2 for
#2, then card 1 for #3 as it did, but when i add #4 it should just use
card 2, instead it conflicts #3 and uses card 1.
