well, it might be amptron. They arent too bad for their board i dont think, but you should try and get the exact model number from him so you can look up the specifics about it.
As for the Via gigapro, i know there is a cpu called a gigapro, but i dont know who its made by, and i dont think its via. It would probably perform on par with maybe a 400mhz pentium. I dont know if it would have enough power to play dvds, unless you added another card with dvd-decoding.
