Thank you my friend I have already download the drivers,and I will try to install it.But I found the Video Logic DVA4000 capture card,it's not similar to the JMC-550,I'm afraid the driver will not works.
Yes my friend you are right it is Beijing Milky Way JMC-550 video capture card,but I think it is a plagiarism product of some brand,so if we find the original product that will helpful to find the drivers.
