Currently, Channels clients are able to change the default tuner settings pulled in from the DVR server when it is first run. This includes which tuners are enabled, their priority order and which channels are enabled/favorites.
In order to enable tuner sharing on a client you need to do several things: enable it on the DVR tab, ensure that all of the tuners are in the same priority order and ensure the same tuners are enabled/disabled. Maybe it's just me, but that's a whole lot of additional trouble to go through.
What I am asking is that when enabling tuner sharing, the client uses the tuner settings from the server, instead of allowing whatever had been modified on the client to override the settings from the server. Otherwise there are many steps needed in order to ensure that the feature works at all.
