- Only do 'lost PCR' checks (r1712) when we're dealing with something that could be an over-the-air transport stream. We can't lose the clock of a program stream and shouldn't have losses on an m2ts stream.

 - Widen the DTS-to-PCR acceptance window from +-5sec to +-5min since there's nothing in the standard that bounds the offset between a DTS and its clock reference.
