I agree completely.
I just got my xbox today (MFT Date 2002-04-10).
When the xbox is a fully fledged mediatermial (as I'm pretty sure it will be one day, through the help of programs like xbplayer) it would be a pity not to use the existing hardware like the dvdremote.
On another note, I read somewhere that xboxes manufactured after Jan 2002 should read CDR's easier, I'm sitting now and toying with different media.
I'm burning an audiocd on a 80min Fujifilm Highspeed (10x) CDRW media now, previous attempts with TDK 74min RefleX didn't work too well (xbox didn't recognice the disc)
