Apologies if this has been asked before but a search found nothing. All the WMVHD material appears to be either 720p or 1080p. I am contemplating buying a second user projector whose only HD option is 1080i. Can it play 1080p (with orr without loss of resolution) or will it need to be converted. Indeed, can it be converted? I will also aquire an i-scan pro with the projector, can this be used at all? Thanks for any thoughts.
