CDS50 connected to SA30 using COAX: can SA30-remote control CDS50?

Hello everyone!

I have my CDS50 connected to the SA30 using a COAX-cable.
My CDS50 is connected to AV, a blu-ray player is connected to BD (for BR-audio).
Now I would like to use my SA30-remote to control my CDS50 but it wil not do that as the CDS50 is not connected to CD. Is there an option to control my CDS50 (connected on AV) using the SA30’s remote?

Kind regards,
Peter Heuts.

Same problem here, although in my case I have it under BD coax input. Anyone able to help?
