I’ve had a situation with one deck (other models were fine) where the “profile unknown” wasn’t quite accurate also. If the error is consistent, the following should work.
1- Do a test insert to see if the record deck’s in and/or out point is off. If they are off, determine the amount of adjustment needed. Then in the profile for that deck adjust the “edit delay” and/or “edit stop delay” values accordingly. (“Play delay” doesn’t matter unless it is also used as a source deck.) Store the profile. Test to make sure it is right.
2- To test the play deck’s accuracy, do an insert (on a known frame accurate record deck) using a window dub or some other source where you can easily tell if you are getting a frame accurate in point. If it’s off, determine the amount and adjust the “play delay” for that deck accordingly. (“Edit delay” and “edit stop delay” don’t matter unless it is also used as a record deck.) Store the profile.
Assuming T/C and timing signals are ok, that should do it.
