Sorry if this was posted before (did a search and couldnt find anything on it).

Anyway, I'm using a DVI to HDMI cable from my cable box to my HDTV. The Hi-Def Channels all look great, however when I switch to a standard def channel, the colors are all wrong. It seems like I'm colorblind when I turn it to a normal standard def channel.

Any suggestions as to why this is happening? Cable is brand new, component works fine (I wanted to use the DVI so I could free up the component on my TV).
