At my new house I'm running into problems. The component RCA cable colors don't match up with the ports on the new Samsung. I tried various combinations but nothing worked.
I was able to use the converter cables that come with the Samsung to get 480p resolution by plugging the AV cables into the Yellow port which looks awful, but was never able to get 1080p by plugging component cables into the Blue port.
Here are pictures of what I have
My Series 3 TiVo:
My new Samsung TV. The plugging into the Yellow gave me 480p. The Blue which is for component video 1080p gave me nothing
