Hmmmmm..... this is hard to answer.
Somebody I know was reading this post, and sent me an email about it. He/she said it best, to be honest:

Not to sound like a 'wise guy', but someone has left a rather comical post in the forum called, "How to author a comparision dvd" (nice job spelling there, heh...)
The author needs to explain to his "friend" how a DVD works (that the medium is almost always prepared with compression introduced) and that you can't make a DVD with an .avi (for example) file and 'preview it on his big screen TV'.
The "friend" is already 'okay with compression' whether they realize it or not (and, of course it almost goes without saying that the party does not realize this...)
You need to spend some more time in the forum section so your members can gain a better understanding of the digital realm and pass on the info to misinformed consumers!

That's really about it.
The only way to do this is to connect a computer to a very large (55-60") screen, and then play both uncompressed and compressed formats on the display using software that doesn't augment the quality in any way. This means no deinterlacers. Beyond that, you'd have to frequently stop and point out exact areas in frames, such as blocks, mosquito noise and color palette compressions.
If you made a DVD, all you'd be doing is simulating errors, and he could accuse you of fudging the data.
Maybe this is an intentional trick question?
