Thank you for pointing me in the right direction. I have one of the ATV on the right Subnet now. One more to go..
Does the Synology NAS also need to be on the same subnet? I can see recording, but cannot schedule any recording.
Does the DVR settings web UI show your tuners?
No web UI cannot find the HDHR by scan or manual IP. I do see the previously recorded shows and I see the NAS in the web UI.
However, the HDHR app on iOS will find, schedule, and show tasks to record.
The DVR needs to be able to see your HDHR. Maybe it's the same subnet issue?
Ok, I’ll keep trouble shooting. I’m not that good with router advanced settings.
