Is it possible to upgrade a video card?

[ro22ko22]

I have DELL Inspiron 700m laptop (7200rpm HDD, 768Mb RAM, Pentium M 1.7Gig) with 64Mb Intel 82852/82855 GM/GME Graphics Video Card adapter integrated into motherboard. As I understand I cannot upgrade the video card to another one with, for example 96Mb, by just changing it. But is it possible to speed up the video card with some software without any harm to the laptop? I need more speed because I have TV capturing card, but when I'm trying to record from TV the video file comes out twitched. I checked the TV card with a laptop with 96Mb video card and video comes out perfect.

If your 'capture' card is separate from your video card, the video card would likely have no effect on capture. If it's one in the same card, there's not much of anything you can do. The amount of memory is more a function of display, not capture. With capture the limiting factor is generally your CPU. You can download the latest laptop video card drivers, but that's about it. You might be able to shut down some background processes and make some improvements. Which do you have a video card and a capture card or are they one in the same?

For a laptop, the better solution may be a external capture device, maybe USB or FireWire.

I have KWorld NV 100 PCMCIA TV capturing card for laptops. I think it means it's external capturing card.
The KWorkd NV100 made on Philips SAA713X Hybrid Chipset.
Any ideas?
