18474a66c6 MTC slave: set initial framerates to current value.

a3a398242b tigten LTC Slave resolution. 
The reason for this is that the LTC generator uses the slave's
resolution as watermark for max-drift, resync. A possible drawback:
session-process will force silent rolls if the delta is larger
than the resolution. LTC has a carrier freq of ~2kHz, choosing
half of that seems a good compromise.
