I've been looking at Hauppauge cards for the last week or so...you did the read the user comments on that 2d device you linked to, right?
I've had various tuner cards for about 10 years now (I think)...Pinnacle, ATI AIWs, Hauppauge...and I no longer consider ATI products.
Buying a tuner card ultimately comes down to...what tier do you want to embrace?
Example: I care less about HDTV capture capability or HD at all...I'm a person who finds that I can't get into the "Wow!" mentality that is designed to sell products to impressionable consumers. So I don't even both considering a card that emphasizes HD capture...unless it also features analog (TV) capture via cable. I capture from my cable service and this is what I need.
I've convinced myself that the HVR 1800 is what I need...but I see the 2250s being offered for just a few dollars more, $108, and that's probably the way that I will go.
The one thing that I will say about capture cards or video-editing software...research the product and company first. SiliconDust may be a technology leader of some sort...but I've never heard of them or their product until you posted. I don't think that's a good thing for anyone considering a purchase of anything ostensibly developed by them.
Another key item...always check the support site (drivers/FAQs, etc.) to see the lay of the land.
Lastly...do a Google search for said product and precede the search phrase with "problems with" and you eliminate the possibility of failing to know something that everyone else knew was a problem with a given product.
