When I visit http://getchannels.com/dvr, I see the following link to my DVR app (running on My Cloud NAS):
http://dvr-MyCloud.local.:8089
However, ‘dvr-MyCloud.local’ does not resolve to anything. If I remove the ‘dvr-’ and just navigate to http://MyCloud.local.8089, it works fine.
I believe you’re using Multicast DNS to resolve these host names, so presumably the DVR app (or the MyCloud NAS) should be responding to ‘dvr-MyCloud.local’ MDNS lookups?
