My television only has one HDMI input and 2 component video inputs. My cable box has DVI and component outputs. I have found the DVI output better but I would like to use the HDMI input for my DVD player.
Anyone ever use a DVI to component video cable? I'm half thinking of trying this but is the reason the DVI output looks better because it is feeding a "digital" input?

DVI is an 8 bit RGB signal, while HDMI can be 8 bit RGB, or 8 bit, 10 bit, or 12 bit YCbCr. If you have a DVI source and DVI display, there will be no problem. If you have a DVI source and an HDMI display, again, no problem. If however, you have an HDMI source and a DVI display, the below-black video information may be lost in the translation. There is a bug in the Silicon Image HDMI transmitter that pops up when converting YCbCr to RGB. The HD TiVo and Pioneer 59AVi do not have this problem.
Even though source information (DVDs, HD) is all 8 bit color, if DSP is applied in 8 bit, such as in a video processor, rounding errors will toss out some of the data. On the other hand, if the data are 10 bit, such as with YCbCr, then the rounding errors don't occur. In fact, 14 - 16 bit is optimum for processing. Also, DVD data are YCbCr, and are converted to RGB in the player for the DVI output. RGB cannot represent all the data in YCbCr, and this is why the below-black information gets truncated."Each problem that I solved became a rule which served afterwards to solve other problems." - Rene Descartes (1596-1650) -

These are for special NonStandard devices that support such a cable.
Lets focus on what you want to do not on what that cable might be for.
You have one HDMI and two YPbPr inputs on your HDTV.
You have a HD cable box with DVI-D and YPbPr out.
You have a non-highdef DVD player with HDMI and YPbPr (480i/480p) out.
Your only true HD source is the cable box. Normally it would get the DVI-D to HDMI path. Your DVD player upscales to HDMI but I assume it doesn't upscale to YPbPr.
If you want HDMI for both, you need a HDMI switcher and a DVI-D to HDMI adapter cable for the cable box. These aren't cheap. There are passive and active HDMI switches. Otherwise change one of your paths to analog component YPbPr.
If your HDTV is average (e.g. 1366x768 flat panel or CRT), HD cable over YPbPr will look close to HDMI for quality. If you don't want to buy a HDMI switch, use YPbPr for cable and HDMI for DVD.
The Cablebox to HDTV cable would look like this
Usually the cable company supplies this cable (free to you).
DVI connectors carry the one or more of the following depending on the specs of the device.
DVI-D - Digital RGB or Digital YCbCr
DVI-A - same as VGA with analog RGBHV** pins
DVI-I (as found on most computer display cards) carries pins for both DVI-D and DVI-A
**Some NonStandard devices send YPbPr over the DVI-A RGB pins. They only do this to save installing 3 YPrPr RCA connectors. That is the application for the cable you listed. The Product description should say DVI-A not DVI which most people would assume means DVI-D.

Most newer cards support YPbPr from the TV port.
