TalkingSoft.com Forums: XviD and MP3 interference - TalkingSoft.com Forums

Hi everyone,
i've just finished doing a clean reinstall of winxp on my fujitsu-siemens centrino 1,6ghz 1gb ram laptop, but encountered an issue that didn't occur before.

i noticed that when i open movies that are encoded in xvid and use an mp3 video stream there is a noise at the beginning of each file which stays as long as there is no sound being played -- e.g. during the intro of a movie. this problem occurs with all kinds of players, except for videolan's vlc media player.
i'm using xvid 1.1.0 and several mp3 codecs such as lame mp3 acm and the frauenhofer mp3 acm codec, but lame is usually my default. i tried deactivating the mp3 codecs and uninstalling xvid, but the problem still persists. the funny thing is that, once the video has been loaded into the player, i can stop or rewind it and the noise won't come back. it's only audible when a "fresh" player has been opened and nothing has been played -- which means that you hear the noise every time you double-click a movie file, the default way of opening a video file for me.

there is no such noise when i open an xvid movie with ac3 audio streams or when a divx file uses mp3 audio streams. also the noise is slightly different from file to file, depending on file size and the bitrate used -- but it's always very loud and unpleasant. i used avicodec to determine which codec is being used and changed the priority of audio codecs using windows' device manager.
any suggestions about what could cause this problem? is there a tool i could perhaps use to determine what the cause is?

thanks in advance.

Wow, there's really a lot going on here

Well after fumbling around for a few days, I've figured out what the problem was. I accidentially installed a new MP3 codec (the Frauenhofer version from this website or the Radium codec, can't remember which one) which replaced l3codecx.ax in C:\WINDOWS\system32\ -- the only thing I had to do was to restore the Windows default one, which can be done, for example, by obtaining the original file from another installation of the same Windows version and then using regsrv to register it or by running the Windows setup on your existing installation. Whichever way suits you more.

Just in case anyone was interested

Which one Of XviD codecs are the best?And one more question I want to encode clip with XviD decoded codec so I have to use Xvid codec I can't use any other codec?
