Cable local channels visible in WMC but not NextPVR

Since you state that you don't have a "cable subscription", I presume that you don't have a CableCARD in the HDHR Prime. Is that correct? This would be consistent with your statement that "The channel lineup shows no Tv channels." because you don't have a CableCARD with a corresponding valid cable TV subscription lineup.

So, what I think that you are saying is that since Comcast has run a cable to your house for your Internet, you are/were able to receive and view Clear QAM channels (ones that are totally unencrypted by Comcast) even though you don't have a subscription for those channels via cable. I believe that in most (all?) markets, Comcast has eliminated Clear QAM channels specifically to prevent customers from doing what you describe (using a cable connection provided for telephone and/or Internet only to also receive cable TV channels). Here in St. Paul, MN, they made this change a couple of years ago and required all TVs and other 3rd party devices to use Digital Tuning Adapters (DTAs) or CableCARDs. NOTE: This encryption is different from the Digital Rights Management (DRM) that can be enforced through CableCARD devices (the "Copy Freely", "Copy Once", "Copy Never").

Actually i still have my CableCard. When i cancelled my cable subscription Comcast didn't ask for it back. Using the HD HomeRun Prime with CableCard inserted, i'm able to tune local broadcasts using WMC (every other channel gives subscription required message).

I can't do this using NextPVR.

So, if you go to the HDHR Prime's web page on the Main Menu, does the Status section show "Card Authentication success" and "Card Validation success"? And if you click on Channel Lineup and then Detect Channels, you get an empty channel lineup list?

Yes.

Card Manufacturer Motorola
Card Authentication success
Card Validation success
3DES encryption supported
OOB Frequency 75.250 MHz
OOB Lock 2.048 Mbps
Signal Strength 88% (-7.6 dBmV)
Signal Quality 100% (38.9 dB)
Channel List cablecard-oob

The channel lineup only shows a bunch of FM stations. Which makes sense since i don't have a cable subscription.

However i can still tune into the local channels from WMC.

My feeling is that if you can't get a channel list on the SiliconDust software, then you have to resolve that before anything will work in NPVR. It seems like WMC still has the channel information from before, but I'm willing to bet that if you wiped WMC and did a clean setup that you wouldn't get any channels there anymore either.

I suspect a HDHR Prime will only work in NextPVR with a cablecard and subscription.

It'll ask the HDHR for the channel list by loading the data from this url:
