Moire can be combated with the sympathetic application of guassian blur on your timeline. 0.5pixel on everything, rising to .75 for geometric shots, to 1 on geometric shots with movement or very very fine patterns.
Works for me and doesn't visibly soften the image (1 starts to a little, so use sparingly, usually the lesser of two evils) the other key thing is to make sure that every stage of encoding is done as progressive.
So if you transcode your footage select deinterlace or a progressive option. When starting a sequence in your NLE make sure it is a progressive sequence, make sure your NLE has interpreted your footage as progressive. Re-interpret if need be.
When you burn to disc use manual encoding and make sure it is progressive. Most HDMI connected BD, DVD and TV's detect and communicate the correct signals, but if there are problems don;t be scared to check that everything is singing from the progressive song sheet.
I am not saying that moire is not a problem, just that if you are serious enough about your video for it to matter, then there are simple things that can be done to reduce it's occurance.
I see a lot of stuff from DSLRs on TV that has not be properly treated, so don't take it as a sleight.
