I have an integrated 64megs SiS 630ET chipset video card on an ECS P6STMT socket 370 mobo and got strange stuff going on. When I played dvd movie on the videolan with stock 2001 dated driver from microsoft xp cd it runs fine but when i tried to put the driver update the dvd reader begin to lag and rush. I tried first the driver version 2.03 from ECS website and then after the 2.09 from SiS itself. Same problem with both. Is there anything I should know ?
