Alright, I don't feel great about making my first post here in a months-dormant thread, but this has been bugging me for a while.
Right now, the only program I have that supports recording from HDHomeRun Premium TV is Emby Media Server. It records from it well enough, but the options for scheduling and filtering recordings are pitiful compared to JRiver.
My HDHR Prime, which I run alongside my Premium TV-enabled Quatro, has been running exclusively through JRiver for a long time and I couldn't be happier with how that setup works. It's just a little disappointing that MC 25 is out and I'm still stuck with Emby's recording functionality for most of my tuners.
I use PercData for my channel listings, and MC 25 (and even MC 24) could see Perc's lineup for HDHR Premium TV in the settings. MC just can't access the channels on the tuners, even though MC can access the Quatro's OTA channels fine.
So, I guess this post is meant to make sure this feature request doesn't get totally forgotten. It's a feature that I've been waiting for a long time.
(If you're wondering why I have both Premium TV and a Prime, it's half a way to get extra tuners for cable channels and half a way to reach some channels that Comcast have DRM-encrypted. Not super cost-effective but I'm generally happy with it.)
