As Windows Vista doesn't work well with analog USB 2.0 capture, I am considering buying a Firewire device... Sonotaco already suggested the Canopus ADVC 55. There are not many options actually (ADS Pyro, Datavideo DAC-200)
I looked for something that would give square pixels and a bigger image (768x576) and found one, the DFG/1394-1e from theimagingsource.com:
http://www.theimagingsource.com/en/products/converters/dfg13941e/overview/

I don't think anybody here has experience with it yet, but it sounds like a good option for a PAL camera (also expensive, but at least with best resolution possible).
There is a lot of info behind the tabs on their site. It should work with programs using DirectX. What do you think? They also have a similar high resolution USB card. Note that they list Vista compatibility for Firewire but not the USB, consistent with what we concluded here.

cheers,
Oscar

Hi Oscar

Thank you for introducing an interesting products.
Their site is documented very well. It seems Imaging Source is reliable maker.

From their documentation, DFG/1394-1e and its driver IC WDM V2F TIS seems to have compatibility with UFOCapture.
It seems that DFG/1394-1e is not using DVSD internal video format but uses UYVY or other formats for capturing. It is similar to other analog capture boards. That is why DFG/1394-1e can have square pixels.
Probably, it may work very well, but I am not sure, because the interface of DirectX is very complicated and I was always using Microsoft's standard driver in case of using IEEE1394.
(Canopus ADVC 55 also can handle 720x576 with Microsoft's driver but its pixel is not square, because its format is DVSD)

About Vista and USB, things did not change at all. Apparently, Vista is very heavy in many cases.
I am waiting SP1 for Vista now.
