In 0.25, apparently code was changed so that every time you jump to a new 
channel (you'll notice there is no stutter if you scroll horizontally across 
the time), some stuff including a sql query is done to determine if the 
channel you just navigated to would be tunable (i.e. it doesn't have a 
scheduled recording with new free tuners, etc).  The "stuff" that happens 
causes the stutter while it processes.  I agree, it's annoying, but 
apparently necessary.
