LA40530 LCD: When playing movies from USB stick, no surround

My Samsung LCD is connected by digital optical cable to DVD/HomeCinema (combined) system for sound (and HDMI for video). And when I play DVD's everything is great. But when I try to play movies from USB on TV, I don't have surround sound - just get the usual stereo.

I would apreaciate any help.
DVD/Home-Cinema is Sony's DAV-DZ330

This one was answered before.

There were a few causes. One was that on some models, surround only works from some sources. The other reason is that most video files I find are simple stereo.

Thanx for the reply

well in my case, I tested on several movies, all of them Blu-Ray rips, that when played from DVD have great surround.
Can you confirm that my model doesn't support surround from USB? The manual doesn't say anything about it.

Blu-ray rips? Why?

I'd go back and play it directly from the BD to see if that works. If that works then you have a mystery to talk to the folk you bought the ripper from.

Support for BD ripped content is going to be hard to find.

Not just BD-rips

It was just an example Happy Any digital movie I tried to play from the USB doesn't have surround. MKV, xvid, divx, avi - all from DVD rips (or BD rips) have the same issue.
I'm really lost here. Are there any other forums you would recommend trying?

The ones that discuss HDCP, DMCA, HDMI and more.

But the issue is too well discussed that some source won't pass more than stereo. I hope you understand that most of this is about "the dang rules" of TPTB and their hope of protecting content.

I'm sure you know more than we'll discuss here about how this all is creating questions like yours.

The only fix I know of is to connect video source to the home theater thing like the Onkyos and then on to the HDTV.

Your setup is one that fails for myriad of four letter reasons. It's not busted but was made that way to hobble and cripple rips and more.
