Yes if you use JRMC MediaBridge (MB) is not required as NR communicates with JRMC via the remoteserver.dll plugin in the JRMC directory. All MB gives you in this case is that it will keep remoteserver.dll up to date. It can become out of date by installing a new build of JRMC so if you are happy to keep it up to date manually in such circumstances and won't be running other media players you don't need to run MB. That's what many of us old-timers do here.
