Thanks, I had just started looking into doing that
what condition would I need to use in the other renderer that I want to use for Live TV?
Update: I have managed to set Live TV to use EVR by specifying containers (mkv; avi; mp4 etc) in the MadVR conditions however, I am now only getting 2 channel PCM instead of multichannel over HDMI
Solved: I noticed that audio was now using Direct Sound due to the custom Audio Renderer. I removed it and everything started using WASAPI again
Thanks for nudging me in the right direction, your help is much appreciated, especially on xmas eve
