Is AverTV Studio or MSI GF4 4400 capture better than this?

[vulcan4d]

Here is a sample (~4mb Mpeg2) a friend of mine took with his Zoltrix capture card.

The quality of it is pretty good, but not exactly what I'm looking for. Now I can go with a AIW 8500 128mb but it's too expensive, and the DV version is crippled.

I was thinking of either going with the MSI GF4 4400 (yes it does have S-Video in), or a regular video card with a AverMedia AverTV Studio capture card. Problem with these capture solutions is I have no idea how well they capture. Could anyone with either of these graphic/capture card compare how well they capture when compared to the sample I have provided above? Thanks a bunch for all the help.

can u fix the link ?

I'm capturing with an avertvstudio and cyberlink's powervcr2 pro straight from Betacam, DVCAM, MiniDV, Umatic, SVHS, Hi8, VHS and 8mm and have found that quality from digital formats is rather better than analog, because they are Time Base Corrected.
If a run my analog tapes throuhg a TBC the quality is really amazing for such a cheap card. I have had many more expensive solutions and this one only has given me one minor problem: I can't capture and encode mpg audio realtime at 48 KHz. It switches to 44.1 instead. My Creative PCI128 can capture normally at 48000 and even has a digital IN/OUT port.
Does anyone know how to tweak powervcr2 pro to capture at 48 KHz? I think it's a software problem.
I'm doing commercial DVD authoring, BTW.
