Canon 5D downconvert KONA LHI

I have had a few discussions with friends lately and would like some feedback on using ProRes 1080p/23.98 Canon 5D footage and outputting through a KONA LHI for a SD DigiBeta layback.

I set my Video Playback setting to 1080psf/23.98 10-Bit and then set my down-conversion to 525/29.97 in the KONA Control Panel. This seems to work fine but others have set the Video Playback to 1080i/29.97. This introduces a 3:2 cadence before the down-conversion, correct? Is this a better workflow?

Also, I am curious as to why there is so much aliasing when the Video Output is set to a 720P setting when using 1080p footage. I switch between 720P and 1080P sequences a lot and sometimes forget to change the Video Playback settings. I'm guessing it's just because the video input is wrong but I have noticed that the picture looks sharper on SD output when set to 720P but tons of aliasing so it's not useable.

Use easy setups. Your life will be a whole lot....easier.

Just use the 525 settings to downconvert. Use the 1080i output when staying 1080.
