    the industry will heavily push HDMI due to the HDCP Digital Rights Management technology

    The difference between DVI and HDMI are as follows:

    Digital Visual Interface (DVI)
    •DVI was developed by Digital Display Working Group (DDWG).
    •It transmits digital video signals. Depending on the version, it transmits video signals in digital or analog format.
    •The equipments where DVI is widely used are flat panel LCD computer and digital projectors.
    •There are three versions of DVI; DVI-A, DVI-D and DVI-I. DVI-A transmits video in an analog format. DVI-D transmits video in digital format. DVI-I or integrated mode can transmit video signals in both analog and digital formats.
    •DVI is like a computer connection with a large connector and a series of pins at one end.
    •No provisions are made for the security of the content.
    •As compared to HDMI, DVI is more affected by noise.

    High Definition Multimedia Interface (HDMI)
    •HDMI was invented by Hitachi, Philips, Sony, Toshiba, Thomson, Panasonic and Quasar.
    •It transmits audio as well as video signals in digital format.
    •HDMI is used in set top boxes, personal computers, video games, blue ray disc players and digital TVs.
    •The versions of HDMI are; HDMI 1.0, HDMI 1.1, HDMI 1.2 and HDMI 1.3. HDMI 1.0 does not transmit DVD audio, but HDMI 1.1 supports the transmission of DVD audio. HDMI 1.2 acts as an interface to computers. HDMI 1.3 backs color support. It is the only cable provided with PS3. Hence HDMI 1.3 requires larger bandwidth.
    •HDMI cable is like a USB cable, that slides into the slot of the source device.
    •Provisions are made for the security of the content. A digital copy called HDCP is used for providing security.
    •HDMI reduces the amount of noise.

    Cable quality, in general, should not be a significant factor in the DVI/HDMI versus Component Video comparison, as long as the cables in question are of high quality. There are, however, ways in which cable quality issues can come into play. As we make the cable longer and longer, the difficulty of reconstructing the bitstream increases. At some point, unrecoverable bit errors start to occur;

      As for cable quality and price the general rule is that up to 3m you are fine buying the cheapest one as long as the HDMI version matches your requirements.

      For cables longer than 5m (or shorter cables with strong interference sources) you should buy at least medium quality as in medium price.

      Just don't fall for advertisement like golden connectors and stuff. HDMI is a pure digital signal and those ones and zeros won't get any better. What really mattes are the shielding (as mentioned above) and a connector that doesn't get lose as soon as you move the cable around a bit.

      As for DVI cables I don't recall such a diversity in prices - I would say around 20$ for a 10m cable, ~7$ for 2-3m.
