Absolutely silly as a blanket generalization. But I really would like to get the link to the press blurb that led this person to that conclusion.

There is nothing fundamental to any of the channel coding processes involved that destroy the video/audio. Generally, the video/audio is preprocessed at the send end to some crummy resolution/frame rate/sample rate so that any generic link can support the download of it. This is what destroys the fidelity and affects ANY download.

If the data rate of the clip being transferred is within the range supported by the link, the link can be cable, DSL, or 2CAS (2 cups and a string). Being able to support the transfer rate, and producing a high fidelity end-presentation are two entirely different things.

HOWEVER, a demo could EASILY be staged so that either could be shown to be inferior to the other.

Perhaps the most important point to realize, however, is that there is no single magic number that can be used for cable or DSL capabilities or comparisons. There are dozens of different cable system implementations using different equipment with different capabilities, and many flavors and fragrances of DSL also. General comparisons without specific mention of the system details for what's being compared is nothing more than hand-waving, and inevitably comes out in favor of the author's bias (or induced bias because they didn't do a very good job of crossing their references).
