Works fine for mythtv 0.25/0.26. If you do the same thing with a cband lnb it will locate the channels and add them to the database as expected but when trying to watch tv or record tv it will be unable to. Recording and watching tv from a cband lnb does work in 0.24 however. The issue is nearly identical to the one here: http://www.mentby.com/dg-mailing-list/ Cards tested on: hauppage nova-s plus, hauppage nexus-s OS used: Mythbuntu 12.04, Centos 6.3 Issue also occurs on multiple different lnbs and satellites.

Also in New Zealand if that's any use. " Bug Report - General closed minor unknown MythTV - General 0.26-fixes medium Abandoned cband, livetv, fail,myth 0
