Expert, pls advise.

Last time I used laptop (Fujitsu E7010, 1.7GHz, 512MB) to do VCD capture from my Sony DV camera. The software I used is Ulead Movie Factory. So far the quality is fine.

For some reason, I change the laptop to Fujitsu S7010 (1.7GMz, 1GB memory), same software and condition, but the quality is bad and the scene always flanking.

I heard the video card (chip) contribute some effort in capture, is that true ? The E7010 using ATI 7500 radeon while S7010 using intel built-in graphics.

Can someone help me ??

Thanks in advance
