I setup a MythTV box with a pair of 320 GB drives in a software RAID 1 
set, and blew through the available space in about 2 or 3 weeks. Now I'm 
considering splitting them into two separate drives, or an LVM set.

So how do you configure Myth to "load-share the space across the 
mountpoints?" I looked around and couldn't find an explanation for how 
to do that. The configuration field for the storage path doesn't mention 
the possibility of handling multiple paths. Unless you're talking about 
a setup with multiple back-ends.

Otherwise, I guess LVM will be the way to go.
