The biggest advantage of a lens for me is that it allows you to use all of the display resolution, so with DVD, you may be finding that zooming enlarges the pixels by 33% and looks more blocky, whereas an A lens keeps all the vertical res so the pixel height remains smaller and the image more pleasing.
I first used a lens with a 720 res pj, and the increased resolution was what I found to be a big advantage as I was only watching DVD back then. Zooming worked OK but the image looked blocky and course compared to with the lens. My lenses were a horizontal stretch models - I started with a borrowed H200 lens which softened the image a lot and wasn't really doing anything positive with the image but I could see the potential, so then I bought an H1000 which I could return for a full refund if I didn't like it . That was a huge improvement over the H200 and zooming, so I kept it. I then bought an ISCO II from the avs classifieds just to see what it was like, and found that was a further improvement, so I kept the ISCO and sold the H1000. I later tried it with a JVC HD100 to see if it was up to being used with a 1080 pj and it was, so I still have it. Since then I can't see myself not using a scope screen or giving up the lens until something like native scope pjs come along.

I trust Gary Lightfoot more than James Cameron.
