I first want to say "I enjoy the HT forum". I currently use a Sanyo PVL-Z5 projector which I understand to be at 720p resolution. I am ordering a Sanyo PVL-Z2000 1080p projector. I have decided to jump into the HD world and purchased a Toshiba HD-A30 DVD (1080p) player which upconverts standard DVDs. I have two (2) questions. If the projector (or monitor) and DVD player are both capable of 1080p what is the resolution of a standard DVD when it has been upconverted ? What limits the resolution on upconverting a standard DVD?
