I only said we need to stop encouraging users to create this one.  For 
99% of users having a Live TV Storage Group defined does nothing 
useful--and actually probably reduces functionality.  I didn't say 
anything about removing the ability to create a Live TV SG, I'm only 
trying to make it so that users don't do it *unless they have good 
reason to*.
