I have had the most success with the unit in external sync, but wanted to post this, for information from others. Thanks for your reply, I appreciate hearing about your experiences.
I can sync in 44.1, but cannot with 88.2 for some reason. Perhaps it has to do with the RCA Scenium I am using as a transport, and perhaps it has to do with the cable.
I am awaiting a Bolder digital cable in the mail now, the older 1st generation one used off a guy here, and I am also expecting a 75 ohm Belden 1694A with Canare rca and bnc. If I hear a difference between them, in my system, I will post it.
