Whoa.. $60 component cables?????
.. Never ever spend that much money on cables man. I was talking to this dude from Molex (they are the "nameless" actual manufacturers of cables that other companies buy from and label as their own), and he said that it probably costs them like $2.00 to make an HDMI cable. And he's like "when I go to like Best Buy, I see the same stuff priced at like $50.00"..
Just because you have "Component Output" doesn't mean you want "Progressive Scan". Component output is just a input type (in contrast to HDMI, DVI, etc.). "Progressive" is in contrast to "Interlaced". Two different things. HDMI is the latest and greatest which has high bandwidth for high definition TV. And High definition is not necesarily all progressive. For example, 1080i is interlaced whereas 720P is progressive.
WIth respect to LCD monitors, why would a display fully support 1080i but not 1080P you ask? Refresh rate limitations! (as far as I know)
When you speak of "Progressive", the more important question is the actual display itself. You have to give it what "that" likes. Some TVs "like" to display interlaced signals, simply because that's how they were designed. Others can deinterlace the signal internally without you having to do it on your DVD player. If you are looking for a DVD player that does deinterlacing (progressive output) for under $20, I can pretty much gaurantee that the TV's deinterlacing (if applicable) will be superior.
.. There are "high end" equipment that does deinterlacing superbly before hitting any displays, but those things are frikkin expensive.
Here's a link to progressive scan:

If you need to know more about Progressive vs Interlaced, let me know. In your case, you buying a crappy progressive DVD might actually hurt you than you simply getting a DVD player that has a interlaced output. First of all, your TV might simply "like" to display interlaced in it's raw form. And "all" interlaced to "progressive" conversions ARE NOT EQUAL.
