Ted thanks for this. It got me through an anxious week of worrying about setting up my system now that I have a DirectStream DAC with Bridge 1 installed, and JRemote on an iPad. Prior to finding your videos I was reading everything on the PS Audio Forum about Bridge / Jriver setup and many people there have had issues. After seeing your instructions I just did it and although initially the Bridge did not show up in JRiver, now it does and it's been working fine for two days.
I've been using a Modwright Logitech Transporter which the DS replaces, and have a SB in a secondary system. Controlled with Squeezepad. JRiver is slow to respond compared to Logitech Media Server, but JRiver is much more powerful with everything it can do.
Interestingly the SB in the secondary system shows up in JRiver as a device under Playing Now. Haven't experimented yet to see if JRiver can control it, which seems unlikely.
