iPod Nano Output to Projector: Video Quality

Hey guys,

I'm looking to buy a few iPod Nano's to use when we play video montages to our clients via LCD projector. Before I buy a bunch of these, I'd like to know what the output video quality will be. These are simple slideshow's created on iMovie and currently, we burn a dvd and simply connect the video out from the dvd player to the projector.

I'd like to simplify this by putting the video on a Nano, then connecting it to our LCD projector. Will I get similar results as with the DVD?

Thanks!
