Hi Jl. I use the RT-20 for everything and find it excellent.
I found isolation and conditioning for it's ac power made an incredible improvement for plain CD sound, much of my listening. Never bothered to take out my conditioning and check for any video benefit.
I have a 'very' late model Panasonic Plasma, I think 52" and the upscaling of DVD's through HDMI from the RT20 is as good as the upscaling in a nearly new Sony Blu Ray player-- and it allows me to listen through my sound system :) Do use any isolation for ac power?
