Tvheadend

I'm running Fedora 18 on a HP N40L Microserver under with a DigitalNow Quad DVB-T Receiver (http://www.digitalnow.com.au/product_pages/Quad.html) as a backend server and a AMD E-350 running OpenELEC 3.0.0 frontend.

I was using MythTV (under Fedora 16) as a backend, but ever since OpenELEC 2.95.5 (OpenELEC 3.0 RC5) I have been experiencing buffering/stuttering of live TV every few seconds.

I've never been particularly happy with MythTV and now that Tvheadend timeshifting has matured, I figured I would give it a go

I cloned the git repo and successfully compiled tvheadend (commit e9ce02138e81d0dd94a2b155e57fda282063c008) and ran it with build.linux/tvheadend -C

Going to Configuration->DVB Inputs->TV Adapters, I selected each adapter clicked on 'Add DVB Network by location...' and selected Australia/Newcastle from the list.

There is a service name for all the commercial stations (NBN Newcastle, PRIME, and SCA multiplexers), but the service name for the ABC and SBS channels are all blank. These channels worked perfectly well in MythTV.
