A very nice job on looking at de-interlacing, and I'm going to take a look at that HQV Benchmark DVD, might be nice to have around for $30. While both Purevideo and AVIVO look impressive, Purevideo MPEG decoding continues to shine, while AVIVO looks to do some catching up in the deinterlacing department.
I would have liked to have had them show the results of all 11 of the included tests however. Also, the descrepancy noted on page7 is actually not a discrepancy at all since the scoring is based in part on the time it takes to switch to film mode. The whole point of the test is to score objectively based on result rather than subjectively.
Nice job Anand! I'd love to see more of this kind of Video testing.
