A/V out of sync on movie from external hard drive

by sheislafemme / December 3, 2009 11:08 AM PST

Hi,
My husband and I just bought a Samsung 50 inch plasma model #PN50B450 and a Samsung Home Theatre System model #HTZ320. The HTS has a USB input that we used for our external hard drive that has some movies on it. The A/V is out of sync on only one of the movies, the rest play fine. Plus I started watching the movie on the computer to make sure it wasnt a bad copy and it plays fine on the computer. What could be causing the sync problems and is there a way to fix it?

Also, I tried adjusting the Speaker Delay Time with no luck as well as the AV Sync function which only made it worse. With the AV Sync set @ 0mSec the audio is still off by about 2 seconds and gets worse if I adjust it any further.

Another thing, when I first hook up the external hard drive and it starts to read it, there is a message at the top that says "Codec Not Supported." I didnt think that had anything to do with it since, like I said before, only 1 movie has the sync problem. Am I wrong in my assumption?

sheislafemme,

If only one of the movies is causing this, it may be the way it was encoded, or the audio format isn't properly encoded as outlined in the manual's list of audio codecs that the television will support.

So what would be the solution? Should I download all of the codecs that are supported by the tv and hope one of them fixes the problem? If so where do I put them? Just anywhere on the hard drive or in that particular movie folder?

Thanks for your help!

sheislafemme,

I would find a codec that is supported by the television (listed in the manual) and re-encode the video file. When re-encoding, you'll definitely want to pick a format/compression option that creates a smaller file than the one you currently have.

Ok, I've looked thru every page of the tv's manual at least 3 times and it doesn't mention anything about a codec or which ones are supported. I even Google'd it and couldn't find a list of any. Help!

audio codecs

On most models, the guide has a large (almost full-page) table with "Supported video formats". The "audio codec" is listed in the final column. This table may be under "Playing a movie file".

The problem may lie with the way the original file was encoded, especially if other files play OK.

I finally found it online. It supports WMA and MP3 codecs and DivX video so I just converted the video to DivX and now it plays fine. Thanks for everyones help!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
