In manuals for receivers that I have read , I recall they have specifically said no extensions or hubs. My guess is not because they won't work, but more likely that they don't want to deal with it not working with all of the various connection schemes. If they say not to do it, and you do and it works then great.
I'll try both of the suggestions prior to committing to anything in the wall.
Thanks.
