I'll second that, and note that NONE of these display technologies 
have artifacts that can easily be confused with interlace artifacts. 
Contouring, the lack of detail in dark and bright regions, color 
fringing (single chip DLP) , and colorimetry issues as DISPLAY 
artifacts.

The biggest problem continues to be that which Tom alluded to:

It is very difficult to do a good job de-interlacing in the receiver 
as opposed to using a high(er) quality professional system prior to 
encoding for emission.  It get's even harder if the receiver is 
forced to work with a noisy analog signal (aka cable) or a trashed 
MP@ML encoding that presents the de-interlace chip with excessive 
quantization noise (AKA DBS).
