Got my 350 a couple of days ago and the Optima BG-ZD101 DLP Link glasses came yesterday. All I can say is Holy #$%^. At first, I had my Samsung HL67A750 in the incorrect mode 1 and was not impressed, even though I was getting a slight 3D image. I thought, "Oh well more money down the drain". Eventually, I figured out my error. Yikes, night and day. Incidentally, you need to be in 3D mode 2 on the TV.
So far, I've only watched the Panny Demo disc and Cloudy With a Chance of Meatballs 3D. And a couple other BD discs like Apocalyto and Hell Boy II. No audio dropouts. I didn't expect any. I'm on Firmware 1.61 and I'm not running to a receiver. I'm in the market for a new receiver.
I must say the DLNA capabilities of this player sucks. It's certainly no substitute for the PS3. Once, I determined this, I regretted getting the 350 instead of the 300. But, upon further investigation, I find I got my 350 for the same price as the 300.
So, if you've got a slightly older Samsung (or Mitsubishi) DLP TV with 3D gaming capability, this player works great.
