I have SONY 57" widescreen HDTV and a SONY Cablevision HTDV dual tuner DVR/STB. I connect the STB to TV with component cables. The STB has an HDMI output, but the TV only has a DVI input. Recently, I've noticed a trail/blur when the image moves quickly. I've had the TV for 1 year and never noticed it before. I wonder if it's the STB/DVR. Anyways, will an HDMI to DVI cable help? If so, any recommendations that are cheaper than Monster? Thanks for your help.
