Setting up a G 70 for the very first time

[artoj]

Hi !

After using a Barco for a couple of years I´m now setting up a G 70 for the first time. In order to get it done right I would like to know:

1) Which gives better picture in G 70 - RGBHV or component - if watching DVDs ?
2) If using RGBHV which is better H+/V+ or H-/V- or a different combination of syncs ?
3) The manual says that when doing the set up use int. osc. pattern P2: Since I live in a PAL-land and watch DVDs @ 75 Hz, wouldn´t it be easier to me to use int. osc. pattern P6, which is also @ 75 Hz ? or would this give somehow a dissatisfactory end result in set up in PQ wise ?
4) If I would mask outside of the lens of the G 70 the ABG horizontal line, would this disturb the ABG ?
