You are obviously not trying to use MCE to record TV as CGMS-A is wreaking havoc with reliability of recording, paticularly for Canadians.The general public has no idea what any of that is, except for possibly the 1394 ports.
I only have slight idea what CMGS-A standards are (copy protection?) even after doing a quick Google search.
The FCC knows what all of those things are and sets rules that govern how they are used. The CRTC takes the Rhett Butler approach of not giving a damn.
