Um, channel changes on my TiVo's are instant.  This is on a regular 
TiVo and my DirecTiVo.  The only time they were slow was when I had an 
external cable box and the TiVo had to change the channel using the IR 
blaster.  I will admit there is a slight time delay as the TiVo buffers 
though, noticable if I watch a show on the TiVo and have the same thing 
playing on another TV.

I hope to have my Myth box finished (PVR-250 and pcHDTV) soon so I can 
record HDTV and local channels from cable.
