also, a vga bios does this, it transforms a YPbPr signal to RGB

Try looking at www.intersil.com, I can't remember the name of it but it shouldn't be too hard to find.Also have a look on www.gamesx.com for posts by a user name RARusk, he has had good success with the intersil sync stripper.

ok, i think i found it.

according to this document byu intersil, you can use their el1883 chip and it automitically adjusts for the different signals.

what i dont get, is in one of rarusk's posts (here - last post) he talks about dropping the bottom two chips at the bottom of the diagram.

now, out of the top chip, is the VSync_out the vertical sync, and the Cp_sync the horizontal sync? or am i getting that confused with the H OUT and V OUT of the bottom two chips?

now, the other thing is that they also have this chip, which is auto adjusting. so would it be better to try and get a hold of one of these (see if i can get a sample), as its far less circuitry?

to clearify a bit.  the xbox has no sync signals that can be output on seperate connections on the cable.  RBG needs several connections, R,G,B, a vertical sync, a horizontal sync, and several grounds.  The xbox has no sync signals that are seperate because it includes both H and V sync in the Green signal.  So with the modified bios, the xbox outputs the RGB signals but still includes the sync signals in the green signal (SoG).  but since many monitors dont support this, a sync seperator will pull the H/V sync signals from the G signal.

there are i think ways of pulling the signal off the motherboard, but i haven't tried and i dont know how successfull they were.

LCD monitors are in general not as generous with displaying odd resolutions (like 720p).  my 19" LCD displays fine in 480p, but can't deal with the other resolutions.  Its an Aopen one.  You're probably better of with a decent CRT since you might be able to get 720p, and you'll most likely get a good 480p signal.  The best monitor i've seen was a budget 15" monitor that could display all the resolutions perfectly.

Good luck.

well i doubt that lcd's wouldnt be able to display odd resolutions. if your's doesnt, it would be just that screen
