IrishTR, I feel your PAIN! I am in Buffalo, NY, and just changed over to Spectrum last week. After two trips to the local Spectrum store to get the cable card the installer does not carry, and the tuning adapter that the store associate failed to mention I would need, finally got it up and running yesterday. I too, wanted to use Plex to view and record Live TV. After getting it setup, and seeing all the channels I subscribe to in the channel lineup I was excited to see how the quality of the streaming was on my network.I'm in San Antonio TX our Spectrum has 95% all DRM minus the locals. Found this out after getting the Tuning Adapter as they need it for SDV and the Cablecard. So the biggest hurddle is DRM and only Windows 10 and or old Windows MCE works. No other app or platform allows the DRM channels to work.
So my idea of Plex TV on all my Roku was shot and I wasted money on the Prime. Now Im aiming for full cord cutting and finding that a hurdle to get exactly what I want. The Prime and Spectrum with Plex would have solved all my problems but nooo stupid Spectrum had to add DRM to every damn channel...
So far no windows 10 devices can stream any DRM channels. I just get errors or constant buffering. I also installed the HDHR app on my IPhone with similar results, unable to play content, failed to connect! The only thing I can stream is non-DRM channels. I figured I would try Plex. After running a scan through Plex it picked up only 55 of 349 channels that my Prime unit shows in the channel list. Only the non-DRM can be watched or recorded in Plex. I will give kudos to the Spectrum app that works very well streaming on my Roku TV and IPhone, and yes I get ALL the channels I subscribe too!
So far, I am very disappointed on my Prime purchase so far. I thought I did enough research before I made my purchase of the HDHR Prime unit. Now I put out to the forum and the moderators, is there something I am missing? If the HDHR Prime unit has access to all the channels, why can I not stream them to my devices on my network? I know that wireless devices can be suspect to streaming, but some of my PC's are connected by cat5e cable. My Roku TV in connected wireless and streams the Spectrum app perfectly on the 2nd story. In my opinion it is the app that is the issue here, so Silicondust, get the app updated to work with Windows 10 and IOS. Please!
