60Hz option has disappeared.. ?
 

My XBOX was chipped a while ago... I'm not too sure what chip was put in (as I was not there when it was done.. it's a long story)

Anyhoo, I think it might be EvoX (a previous version), but ever since, the option to switch between 50Hz and 60Hz has gone from the dashboard. As a result, some games dont work, including Deathrow (orig)

Anyone know about this and how I can get the back?

Sounds to me that the Video mode has been changed to NTSC. You will need the Enigmah video mode boot disk to convert back to Pal50/60 and vice versa
