I have seen this before but I occasionally see situations where the
scheduler does so poorly that it doesn't even use a multirec tuner when
possible. For example:
{{{
2013-01-08 00:00:02.853894 I The New Normal - The Goldie Rush 102-11
WGRZ 08 21:30-22:00 2 18 18 A 18 -3
2013-01-08 00:00:02.854015 I Don't Trust the B---- in Apartment 102-936
WWTI 08 21:31-22:00 2 13 13 A 13 -3
}}}
These two programs, on the same multirec, in the same half-hour are using
two different digital tuners (13, and 18).
IMHO, if the scheduler does nothing else, it should, in all cases where
possible, take advantage of multirec, yes?
Somewhat related, there is a example of poor scheduling in the half hour
prior to the above:
{{{
2013-01-08 00:00:02.852846 I New Girl - Cabin 105-7
CITY 08 21:00-21:30 2 18 18 A 18 -2
2013-01-08 00:00:02.853043 I Go On - Win at All Costas 5 WGRZ
08 21:00-21:30 1 24 24 A 24 -3
2013-01-08 00:00:02.853162 I Hot in Cleveland - Tangled Web 100-39
CJOH 08 21:00-21:31 2 13 13 A 13 -2
2013-01-08 00:00:02.853575 I Happy Endings - Ordinary Extraordi 9 WWTI
08 21:01-21:31 3 23 23 A 23 -3
}}}
The reason this particular schedule is so poor is that "5 WGRZ" and "9
WWTI" are analog channels which have digital equivalents which are both on
the same multirec. If the scheduler would chosen to record both of those
channel 5, and 9 programs on one digital tuner then only one analog tuner
would be used for those 4 programs rather than two. Here, this matters
because while one of those analog tuners is recording from a digital STB,
(so clear signal,) encoded by an Hauppagge card the other truly is analog
signal -- so a less than digital-clear picture.
