[mythtv-users] How to record a particular station on only one of many tuners?

[Chris Isip]

Could you delete the SBS channel from the lineup attached to the first
antenna (where SBS is bad)?.  That way myth would always use the other
tuners when it needs to tune to SBS. You are going to need at least two
lineups then.   I have two lineups.  One is for my settop box.  I did this
once for channel 41.  In all other tuners other than the settop box,  the
reception was poor so I deleted it from the analog lineup and kept it in the
set top box lineup.
