Hi,
I'm really sorry I can't help you with your hack, but wonder if you could help me. Just got one of the DVP FX720's and rather disappointed to see it has no zoom function. It does, however, say in the manual that under LCD set up 'normal' or 'full' can be selected - full filling the screen which is what I want. Mine is permanently in full (can't be changed), but doesn't fill the screen?? I'd appreciate knowing what yours does. Many thanks
