VB, it should be kept in mind that what you're asking about isn't upscaling lower resolution signals to 720 or 1080, but simply converting analog video signals on component, etc. cables to digital signals that can be carried on one HDMI cable. No improvement in quality results; the advantage for the user is the single cable; the advantage for the industry is the copy protection inherent in HDMI.
