Hi, im relatively new to video capture, so this may seem like a stupid question.

I have been looking at this capture card for my computer (Buy Compro VideoMate E650 Hybrid TV Tuner*E650 from CCL - Online Retailer of the Year 2008, 2007 & 2006 for laptops, desktops and computer hardware) and it says that it supports 480i/576i component video input. The input that i would like to use is 720i, so if I got the card would it be able to automatically downgrade the input video to 480i or 576i? Or would it simply not work at all? If the later is the case can anyone suggest any adaptor or anything that would downgrade the input so that it would work, or a cheap card that would accept the 720i input?

Many thanks in advance for any help you can give.
