Tvheadend

Hi,

In testing the lstest IPTV network re-write, I have observed that when restarting tvheadend all the services discovered after entering a IPTV mux disappear. When starting tvheadend, the muxes are shown but no corresponding service is loaded...I have tried the various combinations on the Network config, mux config and service config and the issues are reproducable. Steps to reproduce:

1. Add IPTV network - Net Disc.: False Skip Initial Scan: true -> Save
2. Add udp mux - udp url, interface, service name -> Save
a. Service is found - uuid exists in input/iptv/muxes/**uuid**/services directory
3. Map service to channel -> Save
a. XBMC tune to channel works and plays correctly
4. Restart tvheadend
5. Look in the "Networks Tab" and you will see for the IPTV Network (or other name you defined) that the configured muxes are present but 0 services exist
6. Look in the "Muxes Tab" and all the muxes are present but the number of services for each mux shows 0.
a. looking in the inputs/iptv/muxes/**uuid**/services directory shows all the services that were saved when configuring
7. Open mux and uncheck the "Initial Scan Complete" box to force tvheadend to rescan the mux
a. service is "re-discovered" and saved in the input/iptv/muxes/**uuid**/services directory but has a new uuid due to the "re-discover"
8. channel mapping to original service uuid is no longer valid and clients cannot access channel..
