First of all, thanks to everyone for their kind and elobrate input.  I 
really appricate the discussion.    I haven't pulled the trigger yet on 
purchasing the card, and this is my way of doing my homework before 
investing in something.

As far as I understand, the Lite has the old Brooktree chip (for the NTSC 
decoding part of it), whereas the Gold has the newer cx88 chip.  I'm sure 
the cx88 driver will eventually mature to be as stable and proven as the 
bttv driver, so no worries there.  bttv driver seems to have been around 
forever, and hence I can understand your preference of Lite over Gold.

I like the fact the Fusion5 has the 5th generation LG chipset, which is 
why I'm after it.

Woah...slow down now.  This is really interesting.  I didn't know it was 
possible to have a two tiered setup for MythTV.  I might be able to do 
this.  I can't come up with one fast P4 system, but I can surely come up 
with another P-III system (maybe one with an AGP port) that sits behind 
the TV.  How would this work?   What would be the primary protocol 
enabling the two systems to talk and exchange information?  I'll google 
around for this type of MythTV setup right after I finish this email.
