The main problem with external Scaler is you have to do A/D - D/A
conversion then A/D inside the projector, you add noise to video signal
and loose some definition.
If possible it would be better to do deinterlacing in digital domain
before D/A conversion or after conversion inside the projector.

But Uwe you are right Iscan is a very good product (but too expensive in
Europe).
