Can't Get Rid of Prime as Source

As I am getting ready to move and have no cable availability at the new house, I have had my cable internet and tv cut off.

I have removed my HDHR Prime, from my network. I have rescanned with the HDHR configuration tool and the prime no longer shows with my OTA HDHRs.

In Channels DVR, I have tried to remove it as a source, but it persists. The Spectrum TVE source was removed easily. I have tried multiple times to rescan network, yet it is still there. I finally just prioritized it to the bottom am have disabled it on the clients.

Still, it would be nice not to see it listed.

Update to prerelease and it should disappear

Took a day or 2 for mine to drop off when I unplugged them from the network. Ultimately it worked itself out.

Boom...that did the trick. Thanks
