Yeah, you'll lose a whole lot more sleep reading the code to figure out 
exactly what must be defined than you would setting your alarm for 3am 
and doing a 2-minute channel scan on the day of the test.

And, I would lay odds that you will not define the channel correctly 
(not due to any inherent inability or some such, but due to the fact 
that until it's on air, the exact parameters are unlikely to be 
known--you even mentioned not knowing some of the info, which is likely 
important), and therefore, you will have a failed recording while you 
sleep, so you won't have any idea how good the reception will be.

So, I highly recommend deciding which is more important--recording 
something from the 2-hr early-morning test or sleep.

BTW, it would be a /lot/ easier to just manually tune the channel using 
dvbtools and capture using dd than trying to do it through Myth.  You 
could do all that via scripts (assuming you know what you're doing) run 
through a cron job and don't have to figure out the complexities of 
Myth's definition of DVB channels.  And, you won't have to delete the 
channel from Myth at 5am if you don't configure it in Myth.
