Make sure you do the firmware update(s) on the VP50. It is a sweet piece imo. Love the way it delivers a constant sync signal to the projector/plasma.
Do you use IR or RS232, and do you have discretes for the presets? If I remember correctly, the presets store aspect ratios etc. WE have a few clients that are into film noir and old westerns etc. You see the whole gamut of less-common aspect ratios, and subtitle placements etc. so the discretes are sometimes a big tool...but so far we just have to step through them.
...couple a thumb tacks and a stick of double sided tape should hold this baby up...
