Ron,

If you are using the iScan Ultra, I assume that means you can't use SDI. And if you are using the scaler in your projector what does the Ultra buy you?

How you running the 598, 480i or 480p?

I only plan to play films on DVD.

If you think listening to music is fun, try learning an instrument.
