Our goal was to test the case where an end user may want to encode DVDs for use on their iPod, as this would allow us to more easily compare the software to Badaboom. Comparing quality comes out well in favor of NVIDIA on either the 64-bit or 32-bit version of Avivo when encoding to iPod video, so this makes any performance comparison much more difficult. We can't honestly directly compare the two software packages because of the major difference in the quality of output they generate. To further illustrate the point I uploaded a segment to Viddler, but the further conversion to a flash video greatly improved quality. Some of the corruption is still there, but lost is the choppiness and other motion issues as well as the fact that every second or two we get a frame that looks like this thrown in:

Yeah, they didn't care for it much. I find it hard to believe this was the finished product, but I've not had time to look at it.
