IPTV and NextPVR total noobie questions

[VideoHoarder]

I'm currently using SageTV to manage my TV addiction. Due to some recent cablebox issues, I may need to find ways to either tune the RF boxes that would likely replace my current IR-controlled boxes, or acquire shows on my non-OTA channels via IPTV. I'm not sure that's even possible, though, hence my completely uninformed questions. I have looked at the Wiki, and did not find the info I'm looking for. Clearly, I'm lacking some pre-requisite knowledge.

I installed NextPVR on a spare PC (on Windows 10 Provessional) for testing. I was able to scan my ancient HDHomeruns just to play with the system, but really want to see if I can somehow integrate web-based access to my provider. I use Xfinity, and can access its Xfinity stream site through my browser. But it's not at all clear how (or if) to use that as a NextPVR's IPTV device. The IPTV setup asks for a URL of a M3U file. How do I generate such a file, both in general, and (if it's possible) for Xfinity stream?

Thanks for any pointers.

First you would need to find out if your Xfinity streams are encrypted, browsers can play files with DRM, NextPVR cannot.

Then if they are not encrypted then you would need to find out if they are fixed. Typically they were have a temporary token

In the unlikely event that the are fixed without DRM you would need to manual create an m3u file with the http/https URL for each channel that you extract. There are many guides to creating m3u files on the Internet. I don't think you will find this. If they are fixed with DRM, you might be able to use Kodi it can play DRM but only as LiveTV.

I am using a Comcast box with HDMI capture with NextPVR. My experience is here https://forums.nextpvr.com/showthread.php?tid=65526

This isn't really anything built in for this type of purpose. For the most part cable provider web sites are very tied down, and not really designed in a way that third party applications can use the streams.

Thanks for all the replies. I did see mvallevand's linked thread, and am trying to understand it . I'll send you a reply there with some questions.

Typically HDHomerun Prime with CableCard works with NextPVR no?

Yes it works fine, but DRM'd channels won't work they require Silicondust or WMC software so it is possible that you won't receive all the channels you subscribe to.  Many cable companies are no longer have CableCard support too as the laws forcing cable companies to provide them have been dropped.  Both of these vary by provider and even by broadcast area.
