Hey guys! I recently wanted to play some Halo 2 on my original xbox and I tried hooking the thing up into my HDTV but I only get sound and no video... I wasn't sure if something was wrong with my Xbox so I tried it on an old tube TV and everything works perfectly. I only have the original RGB cables that came with the Xbox. I made sure the ports in my TV were input and not output. Do I need an HD cable to play my Xbox on the HDTV? (It's not that big of an issue, I just don't want to spend money if I don't need too.) Or is there a setting on the Xbox so it will work on HDTVs? I don't think I can get into the original dashboard because my father installed XBMC on the Xbox a long time ago. I guess I could reformat the hard drive and all that junk, but I really don't want to.
