 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.
