I think the short summary of Michael's post is that LiveTV picks the "next
encoder" starting with Encoder 1 and working it's way down. If you
delete/add your encoders so that Encoder 1, 2, and 3 are the physical
encoders *then* go back and configure them for multirec, you'll have 4, 5,
and 6 as virtual encoders. Thus, when LiveTV picks the next encoder after
Encoder 1 is in use, it will actually be physical encoder 2, not virtual
encoder 2 and you won't have a multiplex limit until you exhaust your
physical encoders which is, actually, expected behavior.
