Legacy tuners are now supported in Channels DVR.
First, prepare your DUAL with the latest version of the Channels app:
- install the latest firmware via Settings tab
- re-scan for channels via Settings tab
The scanned channels will be saved to the cloud so that other devices do not need to scan again. This includes other ATVs, iPhones/iPads, as well as the Channels DVR software.
On the latest version of Channels DVR, via the Settings tab on the web UI:
- click Scan Network to refresh your DUAL’s channel list
- verify the web UI shows “xx channels”
- click on the channel list to add favorite channels
- click Set DVR Lineup to configure guide data
Let us know if you have any issues.

but… either we’ve got to be able to manually tick them as HD in backend setup or they’ve got to be detected as such to be useful… Seems to me that a job that is fired on completion of guide configuration for a DUAL that records a few seconds seconds from each stream and checks them with ffprobe would probably be sufficiently “automagic”.
