I'm going to be playing back an SD music video. I shot it on a canon XL2 miniDV in 24p 16:9. I will be using a projector (it is HD) to playback on a 110" screen. Do you think I would have better image quality playing the video from a DVD or from a Playstation 3 using a flashdrive to play a high quality AVI file or even possibly H.264... I'm going to test this later but maybe you guys have some thoughts?
In general, the less compression upon export the better the playback
A DVD is, by definition compressed to MPEG2 http://forums.adobe.com/thread/544206
I will GUESS that exporting to AVI will give you the best picture... but, as you say, you need to test
I'd say make the DVD and use the PS3 for playback. It'll upscale to HD if you have the output set right.
