Out of interest (we have such a situation!), what if you have both? If
the video and audio inputs are all co-axial cables, but the output is a
data stream on Ethernet (which provides the info for display on a PC) -
does 55103 take "precedence" over 55022, or vice versa?
My guess is, since PCs are also involved, that you would use 55022 for
the lot, and not 550103 - yes/no?
Cheerfully yours,
