I picked mine up yesterday at Best Buy, I had to call to check stock. This player is still not listed on their web site as of right now. The best buy SKU # is 9244908. When you call your Best Buy this will save you 10 minutes of waiting on hold while they try to figure out what you are talking about. They can also check all other local stores for stock using this number.
Well I played with it for 4 hours last night, very impressive machine. My only concern is it buzzes an awful lot even when there is no disc in the machine. Sounds just like the hard drive in my DVR but this Blu-ray player has no hard drive! I am very bothered by these noises and unless someone who owned a BD300 can tell me this is normal I will probably seek an exchange today, good luck! There is probably no stock available to do so, we'll see! These noises are a constant buzzing, ticking, and sizzling type of noises. They are hard to describe but it just doesn't seem right, the player operates flawlessly otherwise. I want to note that they seem to reduce or go away when a Blu-ray is playing but not when streaming content (Netflix or Youtube) is.
Anyway on to my impressions of the player. The Netflix functionality works perfectly. I was really surprised at the quality of one of my streaming movies which was available in HD ( I think it was called Flawless). It was no Blu-ray but I thought it looked great, certainly many orders of magnitude better than the other non HD movies I streamed from Netflix. The standard definition streaming movies were hit and miss, some were better than I expected, others were exactly as I expected. One glaring omission is that you cannot tell if a movie is streaming in HD until you select it and start playback. This is probably more of a Netflix complaint than an LG, c'mon Netflix label the watch instantly with a simple "HD symbol" on your site so we know if we want to add them to our instant queue.
The Youtube functionality is another nice surprise. Video quality on my 120" screen was far better than I was prepared for. That's not to say it's good, but I expected it to be abysmal. Depending on the clip it ranged from acceptable to good.
The zoom function works great. I detected only minor image degradation when zoomed. It was satisfying to see the movie fill my entire screen, but it was bittersweet because I knew I was truly seeing less picture, not more.
Image quality on Blu-ray is just stellar. At least as good as my PS3. I did not try an SD DVD as I don't plan on watching any in this HT.
So the player is definitely awesome, however it turns out the only improvements for me over my PS3 are Netflix streaming, zoom, and Youtube. Is that worth replacing the PS3 with the BD370? I'm not sure. Add the sizling noises to that and I am left quite torn. This is clearly a fantastic machine, but I sit here staring at the PS3 and the BD370 and the winner is not clear.
