De-Interlacing – Results
De-Interlacing plays a fairly important role in the overall quality score, it accounts for 25% of the quality rating.

From what we've seen it doesn't appear that Video2000 takes full advantage of ATI's adaptive de-interlacing algorithm thus causing the Radeon to fail the Feathering test. This unfortunately hurts the Radeon quite a bit since that test accounts for 5% of the total quality score.
The TNT2 wouldn't complete the De-Interlacing quality tests without crashing, which unfortunately prevents it from obtaining a final overall quality score.
With the exception of the TNT2, the Savage2000 was the only card to fail the Line Flicker test. This test simply tests functionality of the Bob de-interlacing method, and it's very odd that any card would fail, especially the Savage 2000 which has otherwise proved to be a decent solution for video playback.
Video2000 has two other De-Interlacing tests that are run if the card can pass both the Line Flicker and Feathering tests, however none of the three cards that met that requirement went on to pass any of the remaining tests.
Tearing
This test is just what you think it is, it’s the same type of artifacts that you may notice when you leave V-Sync off and you play certain games. This test accounts for 15% of the total quality score.

Only the TNT2 fails the tearing test, everything else passes without any problems.
