I recently installed three jacks on the back of my box Y Pb Pr and switches to pins 18 and 19 (used to enable hdtv) now I dont have access to an hdtv at the moment but I left my AV cable unhooked and booted my xbox then plugged it back in (to prevent grounding of pin 17 and enabling Pal RGB Scart) but I still have SDTV when I hook it back up with no option in the MS Dash to enable HDTV.
I am using a modchip with the IND bios which supports some AV sensor hack so that may be the issue.
Any feedback / help would be great.
Thanks,
Scott
