Is this card worth the extra money when you can pick up other capture cards for a quarter of the price? I have a Leadtek card but when i feed a signal via s-vid i get a lot of interference lines (constant waves), im pretty sure its not the cable since its a good quality one and moving it does not make the interference more or less. I am currently using dscaler. Would upgrading to the sweetspot card give me a better quality, interference-free image? Thanks in advance for any advice given.
