Today, I learned about HD video connectors for non-HDMI devices

From Wikipedia

At work, several of my co-workers have jumped on the fitness trend and are doing the P90X home fitness program in the gym at work.  The video setup is several years old, with an LCD video screen that was manufactured in 2007.  For whatever reasons, hooking up a progressive scan DVD player using standard RCA video cables is causing the image to go all weird, as if one's attempting to copy a DVD onto a VCR without a video stabilizer.

While the DVD player is capable of upconverting to 1080p and has an HDMI output, the TV doesn't have an HDMI input jack, which limited my options for connecting.  Furthermore, the component input jacks on the TV (YPbBr) have coaxial connectors rather than RCA connectors.  Alternately, I can connect the video using S-Video cable, although this is still an analog signal.

What the TV does have is a DVI-D (dual link 24+1 pin) port, although I'll need an HDMI to DVI-D adaptor to make it work.  Luckily, you don't have to spend hundreds of dollars to buy Monster Cable, but if you know where to shop, you can get your needs taken care of for under $10.
