Chinese firm Venturer has apparently been hard at work on a budget HD DVD player, which it's claiming will be out the door and onto store shelves in the US by this holiday season. The SHD7000 should have ethernet, DVD upconversion, HDMI, but the thing only outputs to 1080i, despite supporting TrueHD audio. We don't know just how cheap the SHD7000 is going to be, but entry-level is entry-level, so we expect it'll be less expensive than your other options, save Microsoft's $180 Xbox 360 add-on.
