I have no problems playing any games or media, but when I try and get into the xbox dash to change my widescreen settings, it gives me the #21 error code. I canged this recently to see what it would look like but now it's just messing up my gameplay, as I don't have a widescreen television. Any help is appreciated. Btw the msdash spits me back to evox dash.
Edit** Problem fixed, had to change EEPROM write on settings and change the widescreen option from avalaunch.
