HDV clips in a SD project

[RonnieMartin]

I have a project that is shot in SD 4x3 DVCAM. My B roll clips are HDV 1440X1080i (shot with the new EX-1). The DVCAM images look good but when I import a clip shot in HDV any horizontal lines are jagged and not even. If the camera moves any at all it is worse. For instance I have a short clip where a person takes an object from a shelf and the edges of the shelf look really bad. Reminds me of my old SVHS cameras. The clips viewed in HDV are stunning clear and perfect.

Is there something that I am doing wrong? Is there anything that will help the distortion when down converting HDV to SD within Edius 4.54?

My project settings are: out put format 720x480 59.94 4x3
NX E1 SD NTC
pixile aspect 0.9000
audio rate 48000 hz
sample size 16 bit
rendering format Canopus HQ

Thanks
