Welcome!

Just for future reference, don't start a new thread by replying to a 
message.  It ends up burying your message inside the existing thread, 
so anybody not reading that thread might ignore your message!  (Plus 
some people get annoyed...)

Wish I could say the same...

Heh... well, first of all, you might run into dual-head or Xinerama 
issues, hopefully nothing unsolveable.  You might want to search the 
archives for more specifics.  Also, some video cards (don't know if the 
GF2 is one) only support Xv scaling on the first head, meaning that to 
get Xv on your TV-out you'd have to set up the VGA as a mirror display; 
not what you want.  Like I said, search the archives & ask around; 
there are quite a number of people with GF2s, so odds are you should be 
OK there.

As far as the cabling goes, S-Video is always better, but I don't know 
if you can go 50' with it.  A couple of people have reported success 
doing this on the list, IIRC.  Of course, you'd still have to run RCA 
cable for the sound, I guess.

You'll be able to watch LiveTV on the Xbox as long as the tuner isn't 
busy recording something else, or someone isn't using it for LiveTV 
downstairs.  You can only encode 1 stream at a time per tuner, and 
Recording & LiveTV are equivalent in that respect -- LiveTV is just 
recording & watching at the same time, for a simple view.

Don't know about RF interference issues.  You could run some serial 
cable along with your A/V cables.  You might be able to use CAT-3 or 
CAT-5 wire, using DB-9 (serial)<->CAT-3/5 adapters at either end.  
Again, it's been done, so search the list archives.


Good luck!
