Ahh, the sample is in another thread - I'll check it out when I get home. If John doesn't mind giving me the SPDIF out of the 410, rather than going to DAT, I can test it out. Of course, to do your test requires that I run Spark and not DP4 ... maybe he'll want to run 4021>FW410, or I can test it out if there's an opener.
All to be determined.
