 I've moved this over to mythtv-users.

 I think what I said is self explainatory.

 Thats the thing. I did nothing, at least not on purpose, to cause it. It
just is. I've done > 30 myth installs for myself and others, and all 
have similar change times. (All Slackware, but over the  years a variety
of versions). The closest I've ever seen was a problem with the TTF library 
which one user upgraded.  Downgrading to the one delivered with slackware 
cleared his problem right back up.

 And before you ask, no I don't have a record of what those two versions were.

 At this point someone who is actually experiencing these really long
changes is going to have to go under the hood to find out where/why.
I do have one spot in the code I was going to look at reworking which 
might have an effect for some people (the preloading of CC fonts at 
playback startup) but I have no idea if that will affect many or just those
on really old slow hardware.
