Problem with sound

I have a little problem with the sound on my videos. When I play my movies in windows media player the sound for my movies works fine, but when I try to import my media to screenblast I lose all of the sound. I do not know how to import the sound as well. Is it because the file I imported is impeg? If anyone could help me that would be greatly appreciated. Thanks-

Eric

According to Movie Studio support staff. Movie studio does NOT work with the "mpg" file format, which is "AC3" as I understood him.... so our only option is to convert the AC# audio to a "wav" file... He did not have a clue on how to accomplish this..... I just wanted to pass that along to you...

MPEG and AC-3 are two entirely seperate formats.

MPEG is a standard that can be used to encode either video or audio (in a standard video-and-sound file, the audio and video streams are encoded seperately and interleaved. AC-3 audio can also be interleaved into MPEG, but is a different format, see below). Movie Studio supports both MPEG-1 (the standard used for VideoCD's and most MPEG video you find on the net) and MPEG-2 (the format used for digital cable/satellite video and DVD's) video and audio.

AC-3 is the Dolby Digital Surround Sound audio standard used to create surround tracks for DVD's and in movie theaters. Due to the high cost of licensing this technology (it would likely more than double the shelf cost of Movie Studio), support for this format is not included. Our Vegas 4.0 professional audio/video editing tool does have purchasable support for writing to this format, if you are interested in authoring surround sound movies.

I hope this helps to clear things up. Now on to your issue, Monsta. What type of file are you importing? AVI? MPEG? WMV? Quicktime? If you know the source of this file or what was used to encode it it will help me to determine what codec was used to compress the audio and I should be able to help you out, or at least point you to a workaround solution.
