Mainstream S/W package to take full advantage of ATI 550 H/W encoding

Hi,

I own three (3) ATI TV Wonder Elite boards (550 Pro). Currently I am using them in my XP MCE HTPC, Vista Premium PC, and a video capture/processing PC.

I have read quite a bit on these forums, and it appears that (with respect to video capture from analog sources)

- The S/W (i.e. PowerCinema) that ships with these boards is s***s.
- One needs gbPVR or ChrisTV to make use of hardware encoding offered by this excellent card.

I want to use a package specifically made for video capture/editing. For example: Adobe Premier, or WinDVD, etc. I didn't read anything suggesting that any software packages--other than the two TV watching ones listed above (i.e. gbPVR and ChrisTV)--can make use of H/W encoding offered by 550 PRO card or not. Can someone please let me know of a popular video edit/capture package that can use 550 Pro H/W encoding? If there is none, is there a quality penalty for bypassing it's H/W encoding?

(BTW, I will be capturing video from Hi8 and VHS sources)

THANKS A LOT!

regards,
