I wasn't certain if the 1950 was a dual tuner (both inputs can be used 
simultaneously) or hybrid tuner (only one can be used at a time).  By 
default, MythTV will lock access to digital tuners at all times, to 
prevent getting into a situation where another application has grabbed 
it causing MythTV itself to be locked out when it goes to record.  As a 
consequence, this means the analog half of a hybrid tuner is locked as 
well.  You can disable this behavior in mythtv-setup.
