I have a FE/BE combo, AMD XP3500 which is hooked up to an ordinary 27" CRT
TV through the SVideo output of an NVidia 5200. Apart from changing aspect
ratios with 'w', I have no problems showing live HDTV from the HDHomeRun
on the SD set. Someday I'll buy an LCD to show HDTV, but I have kids.

Your xbox is probably the problem -- HDHR sends whatever it
gets, which is MPEG2 and may be HD. If the xbox can't handle
display and downconvert, you have a problem.
