Vudu in HD streaming business. And for that reason we're happy to see some of our favorite products like the LG BD390 working with Vudu. We had a chance to catch up with Vudu at the LG's CEDIA booth and ask them a few questions. Apparently there were a few changes to the encoding techniques necessary to transition from a disk based device to all streaming, including more profiles to adapt to different broadband connections. We have ot say that our overall initial impression was that the changes went off without a hitch. One question we didn't get answered though was whether or not the Dolby Digital Plus used in downloaded stream could be bitstreamed to an AVR via HDMI -- the original Vudu hardware could only output vanilla Dolby Digital -- but we were promised an answer. In other words you'll know as soon as we do, so in the meantime click through and enjoy the short demo.
