need help editing mpeg audio

[deadliner2002]

i have recently downloaded several mpeg music videos and the 1st thing i want to do before creating a vcd is get rid of the horrible audio, as it sounds like whoever created the videos had the record level maxed out.

is it possible to take my own good quality mp3 file and replace the existing audio track that is in the mpeg video?

if so, please give me some direction on what software i could use to do such a thing, and if i need to convert my existing files to something else before beginning the process.

thanks,
deadliner
