Picked up the HD-A1 last Friday (4/14) at Best Buy. This replaced a 3 year old JVC. I've got it hooked up to a Sanyo Z3 via a 35' HDMI cable and shooting onto an 85" DIY screen. The audio is currently connected via coax to an Outlaw 950. I'm just starting to toy with the 5.1 analog connections. Got it up and running just need to dig in and calibrate. Thoughts... I am very impressed with this machine so far. The picture at 1080i is amazing. Colors are vibrant and very nature looking, blacks are deep and dark, whites are bright, and flesh tones are excellent. Contrast is excellent. There are almost no compression artifacts that I can see. A very, very clean image with outstanding detail. The audio is also very impressive. I noticed a crisper, cleaner sound compared to SD-DVDs. Not a huge improvement, but noticeable, especially with the center channel. The difference in sound between the SD-DVD and HD-DVD of Serenity is actually quite noticeable, not as much with Phantom of the Opera. The few and minor drawbacks are; first off, the remote, it's bad. Small buttons that are hard to read and a poor layout. Also, from the time you power it on it takes nearly a minute before you can access the tray. Once in, it takes about 15 seconds to bring up the movie. Other then that, I can find no other negative issues with it. This player also upscales SD-DVDs to 720p. All I had to play on the A1 for the first couple of days were SD-DVDs and the improvement in picture quality is quite noticeable. So far this is an outstanding performer at a very reasonable price. The picture quality between SD-DVD and HD-DVD is quite substantial. For a first gen player with a brand new format I think it's off to a very good start. Toshibas player, even with its minor issues, is a very well built player with only a few minor issues.
