Pulldown Detection. Purevideo requires the user to pay extra for the Purevideo decoder in order to enable pulldown detection, while Avivo comes with this ability for no extra charge. 3:2 pulldown detection is a pretty darned important feature when watching DVDs, you're definitely going to notice a quality loss without it.
Noise Reduction. Purevideo offers absolutely no noise reduction. Avivo offers excellent noise reduction. Noise reduction is another quality feature that will make a big impact on the visual quality you experience when watching DVDs on a PC.
Those two items are a big deal; you will notice this stuff when you're watching a DVD on your PC. Otherwise, there are some minor discrepancies - Avivo seems to use less CPU power, and Purevideo seems to lock on to 3:2 pulldown faster - but neither of these minor things are a big deal unless you have a very specific personal requirement. Pulldown detection and noise reduction though, those are pretty important.
As far as video encoding, Avivo offers a free encoder I guess, a nice free tool but not the GPU accelerated wonder-software that would make it a must-have.
