Running it now. It will be hard for me to do a lot of truly-live
testing because I almost never record anything from the (SD)
multiplexed OTA channels I have available. I've scheduled all of my
now-six tuners (four multirec OTA, two cable) at once during tomorrow
afternoon, though.
Two questions:
* I've many times before recorded from all four physical tuners at
once, and usually the two OTA tuners are set to non-multiplexed
channels. My understanding is that theoretically, from a disk- and
network-usage standpoint, recording from my now six tuners should be
no more stressful than what I've already been doing (except some
extra load on the MySQL server from laying down six seektables
instead of four). Is this correct?
* Something odd I noticed when scheduling the six simultaneous
recordings is that, when changing an existing recording rule's
setting (Single Record->Find One, Single Record->None, etc.) on an
OTA channel, it does not "apply" until I perform a second action,
either on the same rule or elsewhere.
For example, I create Single Record rules on simultaneous programs
on channels A, B, and C. I then turn rules A, B, and C off in that
order; all three remain unchanged.. I then again turn A and C off in
that order; A and C duly disappear with B remaining unchanged,
proving that it indeed is not a case of the database just being slow
to respond to the rule changes. I did not see such behavior before
applying your patch and again, this behavior only appears for OTA
channels. ('mythbackend --resched' doesn't force the rule changes to
apply, either.)
