Hello,
I am in France. I have a Bryston SP1.
I have a problem on digital inputs.
DVD & LD does not detect input signals? the light is red.
CD & TV / SAT detected ok, the light is green. But does not DTS.
What can be the problem please?
Thank you very mutch 
Hi, regarding your personal message to me on this problem, my problem reads different than yours.
To answer your question though ("Did you solve the error"), I did not receive a reply from Mike and the problem still remains. However, I eventually bought an SP-2 which has a similar problem on some CDs and also loses the first few seconds of audio on DVDs and BluRay while it determines the source encoding.
I shipped the SP-2 in for repair, they made an "adjustment", but its problem still remains.
