Every Ati All In Wonder I have ever owned has sucked, has not worked, or just gave bad quality or corrupted videos. I hope the world of the Mac is better for this.
For quality capture/editing, you should not get this ati cards.. Even a cheap tvtuner based on BT chipset can produce better quality videos, with some tweaking... though the files will probably be big.. If you need hardware mpeg1/mpeg2 encoders, then wintv pvr 250/350 will be even better than the ati all in wonder cards.
