Video started out as analog 8mm, captured to DV avi via passthrough using a Digital8 camcorder. These stairstep "jaggies" appear in certain areas, typically curves and straight edges that go at an angle. They're more pronounced after deinterlacing, noise reduction and sharpening however I also see them when playing the original interlaced video with an analog camcorder through my HD TV, I wonder if it's an artifact of digital conversion?
Screen shot from a frame that's been deinterlaced with QTGMC and denoised with NeatVideo. Thanks for all input.

Don't sharpen so much along the vertical axis. Otherwise, some aliasing is normal for all digital video. If your player or TV doesn't scale well get a better player or TV. Or upscale to a higher resolution in software.

There won't be much difference in terms of aliasing between "medium" and "slower" presets. There will be with some the faster presets which might use bob or yadif for the edimode .
The other suggestions are still valid (don't sharpen as much, add an AA filter)

Seems like I have to settle for either jaggies OR interlacing combing?!
