Well I was tired of waiting for my A2 to come in. I picked up the Add On today at my local GameStop.
I came home and plugged it all in. Installed the software. Shut it down and restarted the system.
I put in KK just to see what it looked like. Movie startup was extremely fast. Pretty much on par with most regular DVD players. I set my resolution to 1080i since my plasma is 1024x1080i native resolution. I was absolutely stunned at how beautiful the picture was. This is my first time seeing an HD movie. I just couldn't believe how awesome it was. I just watched the first 20mins then shut it off.
I came back and put in Aeon Flux. I watched the entire movie and the picture was just as beautiful. No more pixelations!!!!! I selected the DTS over the DD+, but it all seems to be converted into DD in the end.
I have tons of movies waiting to be watched. I'm saving the Dolby TrueHD movies for my A2 so that I can listen to them in all their glory.

I had ZERO audio drop outs or stuttering video as some have claimed. The unit is very quiet as well. With the HT system turned up, you never notice it. Now if only they could get an HDMI cable and be able to decode the newer codecs, this would be a steal.
