Okay this is very odd. I know Spike TV are a little "Creative" in
their interpretation of timeslots, but I have my MythTV box set up to
record any instance of ST: TNG, and that means I get 3 episodes from
Spike TV (Canadian Feed) and one from Space.

I have never had any problem with my Myth box missing the end of the
first episode, and the second (And third) in the run of 3 both start
at the "Copyright Paramount Pictures" screen on the end credits of the
recording before (Reasonable, as Spike don't put an ad-break between
the episodes, just a quick "Now & Next" page).

I have MythTV set to "Extend" recordings 10 seconds on each end (Just in case).

I am using NTPD to time-sync, with the servers set to:

server ca.pool.ntp.org
server pool.ntp.org
fudge stratum 13

With NTPQ reporting:

ntpq> peers

+raptor.tera-byt    3 u  415 1024  377   45.486   -1.108   2.398

So I'm not sure what the problem is here.

As Bugzilla would say: WORKSFORME
