Advice needed

[supplier]

Sorry folks for semi-off topic post. I just got HDTV ready LCD TV Syntax Olevia)and trying to figure out what connection to use to connect HD cable box to TV ; DVI/HDCP or non-progressive Component connectors Y/Cb/Cr?? Y/Cb/Cr is better than S-video, but is it better DVI/HDCP ?

I would appreciate any help/opinion on this matter.

The TV also has VGA connector for the computer. But my computer has only DVI output. Is computer's DVI output can be used with TV DVI/HDCP input ?

Thanks a lot.
