problem1: never happened for me, what dimension are you getting if you just check the image in your os? problem2: dont know what to say about this one, sounds more like a user setting in photoshop then something being wrong with the v5 render? the only thing ive ever noticed is that my 300 dpi renders opens up as 300.125 dpi in photoshop but thats a long way from 72 dpi :)
