Was probably the first to own this TV as I ordered it when Amazon had it up to purchase ($1199 free ship, no tax) at the beginning of November. Originally listed as a 3DHDTV but alas it's not. (been meaning to call up Amazon and see if they'll offer a partial refund or gift card due to the listing error...)... It came on 11/19. Overall, I'm pretty impressed with it. Out of the box I only adjusted the Cell light to 20, the Color up a few notches, and turned off all those Mpeg deblockers and Eco mode crapola...
I also own a LN40C530. I use it as a media player (plug in USB hard drive) and it's played everything I've thrown at it -- bluray m2ts (not re-encoded), h264 TS caps, 720p/1080p mkv's etc.
However, this PN58C500 seemed to have trouble playing back the same stuff via the media player the LN40C530 does without a hiccup! The Bluray playback almost has a 'jerky'ness to it on pans and fast action. Is there some setting I'm overlooking? I didn't change a thing on my LN40C530 to get these files to playback. It also downright refused to playback 25fps h264 stuff (Top Gear UK caps). My LN40C530 plays those back without a hitch! And on some re-encode MKVs (720p/1080p) the audio/video would lose sync if paused, rewound, or fast forwarded. Only way to get it back in sync would be to start from the beginning of the file.
Contacted Samsung via the Live chat, but of course they were unhelpful. "Is the TV plugged in?", "What cables are you using", "Can you see Russia from your house?" ...LOL...
Anywho, reading back a few posts -- what's this about changing it to C590 cinema mode? What's the advantage to that?
