Hello, I am having problems with my DVD Drives. On both of them I can play CD audio fine. As soon as I try and play a DVD, I get the picture but no sound. I have tried with the L/R/G four pin plug in the drive (going to the sound card). I have tried the two pin digital plug and I have tried nothing at all. In all instances I get CD audio. I have tried two different players (WMP and the Creative that came with the drive) If anyone has any ideas I would be very grateful, Thanks, Harold Clements

Have you tried more than one DVD? It sounds like (no pun intended) you need a codec.

Yea, I did read that in my search for the problem but I don't know what codec I am looking for. Any ideas anyone?

Hello Grok Lobster, This program can identify codecs being used. It is called Gspot I think its freeware. http://www.headbands.com/gspot/ If it is a normal DVD I don't think it will be a codec problem. If it is a "ripped" DVD the audio may not be coded at 48000MHZ.

Sorry, I meant to say "if it is a re-authored DVD"

I have just had a look at GSpot and it seems to me that it just examines .avi files and nothing to do with DVD’s (or am I being stupid?). I am trying to play a pre-recorded DVD not rip or a re-author. Any other ideas?

Hello Harold, This seems to be a common problem and it appears Grok Lobster was right. You don't have to find out which codec is needed as other jave solved siminar problems with "codec packs". I found this thread at http://yabb.jriver.com/interact/index.php?topic=20579.msg147817 It has a microsoft link for the default codec pack. This person also had no sound from WMP and another program (which relied on WMP). Here is his solution. "Well, I finally solved this problem, so I figured I'd post what the solution was (for me anyway) in case anyone else has the same problem. I keyed on WMP not playing sound either, as MC seems to use some aspects of that to play DVD's. Hunted around a bit, and finally decided to re-install the default codecs (re-installing WMP was my next option, but I didn't need to do it). http://www.microsoft.com/windows/windowsmedia/download/default.asp has a few codec links. I installed the first and third one, just to be on the save side, though the first one probably solved the problem. While the codecs were installed, WMP didn't seem to think so. After re-installing them, everything worked fine, and now MC displays info under DVD audio decoder properties (before it didn't show anything). Don't know what originally caused the problem, but that's what fixed it." P.S. you're right about G Spot. You might want to update your sound card drivers too. here is a link to the microsoft codec page. http://www.microsoft.com/windows/windowsmedia/format/codecdownload.aspx let us know how you go.
