Which DVI cable? (1 Viewer)

[Nobeta]

I found DVI cables at a certain site for $24.99 and am wondering if they are any good? I cannot post the full link as I have not posted 15 times at this forum, but it is a valid question. Here is part of the link and you will have to fill in the rest.

Comcast recently installed a Motorola DCT5100 box and I don't know if it will take advantage of the DVI cables or how to check? My tv has the DVI connector.

What length cable are you looking for?

I use a 30 foot cable from RAM electronics based on several good reviews. It is working great.

Nobeta,
Call, I recently purchased a DVI cable for my comcast box, and come to find out (after calling comcast), the DVI output is not working on my box and probably won't be working for sometime. I suggest you call comcast and find out if your DVI is activated before purchasing any cables.
Good Luck with this, Jay
