OOOOHHH!
I can answer this now!
But before I go any further, realise that there are probably thousands of posts here and on other fourms about cables.
First of all, the CC guy was "kind of" telling the truth. Of all the analog cabless, the component video is the best. In order, from best to worst (for analog only) is:
Best (Prefered) Component Video
S-Video
RCA
Worst Composite (old RG-59 Cable connection)
But, is is well known, that BB and CC LOVE to sell Monster Cable as the profit margin is HUGE. AND, there are lots of alternatives, and most are just as good, if not better, and often less expensive than Monster Cable.
I have never read any posts that say Monster Cable is bad, just too expensive.
Here is a good article on the different connections
Now, DVI is a DIGITAL connection, a:
"The DVI 1.0 standard was originally created to enable digital-to-digital, high bandwidth data transfer between a computer and a flat screen monitor. However, because of DVIs ability to also process high-bandwidth HDTV video, interest was generated in the consumer electronics industry."
now from DVI, came HDMI, which is:
"High Definition Multimedia Interface is a descendant of DVI. Like DVI, it is a digital cable and connection that supports digital data transmission. Unlike DVI which supports only video transmission, HDMI supports both high definition video and audio. HDMI will offer 'legacy' support of older DVI connections."
So, the MOST prefered video connection is to use the DVI or HDMI connection.
If your DVD only has DVI and your monitor only has HDMI, no problem, just buy a DVI to HDMI cable.
There are LOTS of online places to buy cables, do some searches here to find options.
One place I have found, is that your local Radio Shack seem to carry good quality cables, at decent prices. For anything other than connecting a 10,000 amp to a 5,000 pre-amp, the RS cables should do the trick.
