That's interesting.  I have one FE that will not play live TV without 
AlwaysStreamFiles turned ON (it just hangs at a blank screen for ~10 
seconds, then the "error opening jumpfile") and have never figured out why. 
About the only thing I can think of is this FE is also a SBE (though that is 
now turned off in favor of mythjobqueue) and it has identical folders 
mounted to the the MBE to allow it to do transcodes.  Maybe something to do 
with that?

It's also a little concerning that the setting itself has been removed from 
Myth settings screens (I believe it was gone in 0.24 too,but don't quote me 
on that), but it still seems to have a pretty big impact.
