You did not mention which deck you are using as your source. We use a DSR 1600 player that allows placing the tc window anywhere. You could also use an external window burner, such as a Horita WG-50. We recorder to a Panasonic T2020 for this sort of thing, and it works quite well. I’ve never had a playback problem.
BTW, we also make DVD window scoring prints with TC on audio ch 2. My composer loves this.
