Lag time before record...

In Preferences, tell PTLE to only use 60 minutes worth of space for recording instead of open ended.

ADAT sync...

PTLE is the transport.
MOTU is MTC source for ADAT and PTLE.
ADAT is digital sync source for PTLE.

The Timepiece AV is perfect. PTLE should be set for Optical Sync. You will hear pops and clicks if this is not set to optical.

In "Peripherals" set PTLE to receive MMC. Also, set PTLE to SEND MMC to the MOTU (probably default ID #20).
Put PTLE "online" and hit play (or record...whatever you're doing at the time)

This is a QUICK rundown as I'm in a hurry. I have more for you if you need it. Let me know.
