Without knowing your particular model, I found this info that might help you:
We also tested the Sony's 1080i de-interlacing using the HQV HD DVD, and while it passed the test for video sources, like most TVs it failed the test for film-based sources. As a result we saw moire in the upper deck of the football stadium during HQV's pan, but we didn't notice the issue with the program material.
We've complained in the past about Sony's Digital Reality Creation processing wreaking havoc on standard-def sources, but there's no mention of DRC in the KDL-46S3000's menu system, and the set did a very good job with the standard-def material we tested. Displaying the HQV DVD connected via component-video at 480i, the Sony showed every line of resolution from the color bar tests, and rendered the detail test--with its grass and distant shot of a stone bridge--quite sharply. We were even more impressed by the Sony's ability to smooth out jagged edges from moving diagonal lines and the stripes of a waving American flag. We also appreciated the range of noise reduction controls, which were quite effective--about on par with the Samsung LN-T46651F--at cleaning up the moving motes of noise from the disc's many shots of skies, sunsets, and flowers. The Sony also engaged 2:3 pull-down quickly and effectively, removing the lines of moire from the grandstands, although it was a split-second behind the Samsung. All of these tests were conducted with the CineMotion setting at Auto; we found no reason to turn it to Off.
