I have a Dell Latitude CPx. 500mhz CPU, 128MB ram (just bought 512 on Ebay should have in a couple of days, 70Gig HD, running XP Pro. I have a few movies and other vidieos on the computer, so I connected the computer to the TV using the S-video port. However my video card (8meg ATI Mobility M1 APG 2x)doesnt seem to be powerful enough for the task. Any suggestions to upgrade my video capasity?
