How to do with AC3 (too low volume)

[kthan]

I had some xvid viles (with AC3, 448kbps) and they had too low volumes (I can barely hear the sound even at max volumes).

Does this something to do with its higher bitrate? How to resolve this issue? I opened Soundforge 8 (to nomalize the file again), but this cannot read the file. Is there any plug-in to read xvid? Or, do I have to save it to wav. and reprocess (but, I don't think I can reproduce xvid<ac3> again in soundforge).

Since I will view the files in divx-compatible player, I need to keep xvid format (not encode with MPEG2). Please advise me the best (easiest) way to do it.
