Hi.
My system has Asus P3B-F, Diamond V550 16MB and a Pinnacle Studio-PCTV Tv-tuner.
I have no problems capturing and editing video.

I'd get a motherboard having Intel chipset instead of VIA, if I were in your shoes.

I agree with Shawn about Abit. Asus and Abit are both very good motherboards.

Just one tip: Avoid cheap motherboards. Video capture needs powerful and branded hardware.
