Oh, duh! I totally forgot! Anyone else remember that the XBox has  
only 64 MB of RAM? It's got to swap out stuff in RAM to make room for  
the player, OSD, etc.! *smacks self for forgetting*

Probably swapping. I remember that my iBook was hells slow before I  
got my RAM upgrade. The use of swap space is slowing everything down.  
Taking longer to load LiveTV is the usual LiveTV delay, except  
exaggerated because of that swap issue.
