Best option for PVR?

[vandey]

So I'll describe my setup here. I have the SiliconDust HDHomerun Prime tuner with cable card provided by Comcast. I live in North America and I am looking for the best PVR backend that can run on the Pi 2, and can have the front end working on the Pi 2 as well. I've tried to install tvheadend but it looks like the DVB-C doesn't have the US networks available. When looking around for solutions it seems that tvheadend won't work with the HDHomerun Prime using the DVB-C settings. I can try to set it up as IPTV which isn't an issue but the configuration isn't that easy to look at.

My question is, what is the best PVR backend that can run on the Pi 2 and has a supported front end in Xbian? I've looked at VDR but in VDR do you have to have that running on a different machine? If not how do I get VDR configured with my HDHomerun Prime?
