 FYI this varies a LOT from user to user.  My LiveTV takes 2 seconds to start,
and channel changes are 1.4 seconds. And yes I timed it. It use to take longer
but after Isaac did his rewrite it. I never really use it, except for short 
tests after hardware changes to make sure I haven't messed something up :)

 I don't know what it is that makes it so different from user to user but if 
someone ever does track it down it will make a lot of people happy.

 And for the curious this is with PVR 250's, Nforce2 board, xp2500+ and 
512Meg of ram. Timing from the remote frontend shows the same startup 
time but channel changes are 1.8 seconds
