Tvheadend

Longish intro. After much trial and error I had managed to get TVHeadend working on my system. What I have are XBMCbuntu appliances on each of my TVs, and an Ubunutu Linux 12.4 file server running TVheadend as the backend PVR on the network. I'm using an ATSC Antenna attached to a HD Homerun dual ATSC tuner.

As mentioned, I had everything working by following your detailed instructions. Then two things happened. The first is that I reserved the file-server IP on the router, the second was that the road in front of my house was regraded and they accidentally cut my Internet connection. These two things happened at virtually the same time. (yes, I have rebooted the server)

Since those occurrences, I've had a string of failures. The first was XBMC appliances being unable to connect to TVheadend PVR service (even though my internal home network was intact). TVheadend continuously shut itself down on the file server despite my efforts, until Internet service was restored 3 days later. Once service was reactivated, the XBMC appliances began throwing a new error, that TVheadend could not make any connections.

I went to the file server to investigate. I could watch TV on the file server using the HD Homerun utility, but could not on the TVHeadend interface. Upon further investigation, TVheadend appeared to be trying to do initial scans on the Muxes again. However, it constantly would get stuck somewhere in the process.

At this point I've tried:

Updating TVheadend to the newest version
Deleting all the muxes
Deleting all the mapped channels

All to no avail. TVheadend gets stuck someplace in the middle of the scan. I've left it for periods of over 12 hours to no avail. (The last 3 times I've tried it's gotten stuck at mux 27, but previous to that it was different numbers).

I've attached a screen grab if it's of any use. Could really use some help here.
