I have been working with the production model of this piece for the past two weeks. I've tried it on a Marantz Vp12S3, a Sony VLPHS20, VPL400Q, KV34XBR910, KDF60XBR950, Pioneer PRO1000HDI, and several LG, Runco, and Fujitsu plasmas, as well as Mitsubishi RPTVs.
As stated above, Disney releases disable the scaler and only 480p is available on the outputs. However, all other tested commercial DVDs output at any selected resolution, including 720p and 1080i, on Component, DVI, and RGB outputs.
On the fixed pixel devices, the 720p output is preferable. The picture is quite sharp, with excellent color and no noticable artifacts or ringing. Edge enhancement is not an issue at any image size.
The Mits RPTVs and the VPL400q (which does not display 480p/720p) really loved the 1080i output.
DVDs have never looked better on any of these devices. Since the scaler (an OPlus Rembrandt?) works from the pro level (straight digital) the cost-to-performance ratio is way out of wack.
The ATSC/Quam HD tuner is a nice bonus. Pictures from rooftop antenna and Comcast cable were both excellent - better than any Gen3/4 tuners I've seen. Maybe these Gen5 ones are the real deal. Of course, since LG holds the ATSC 8VSB patents, the tuner performance should be no surprise.
Actual street price here in Sacramento is below the stated 599. This player is for real. PRO Group members and Best Buy stores will have access to the line next summer. Until then, only the LG retail partners will be supplied (or so they say).
There is also an ATSC/NTSC 120 gig HD PVR due to ship shortly, using the free TV Guide programming grid.
