hi how do i turn AC3 audio into mp3. the reason is ive got a simpsosn dvd which ive ripped with smart ripper. i have then used dvd2one to turn the dvd into small vob the size of 470 mb. the problem is i am wanting to put two of eposodes onto a single cd disk is there any way i can turn the AC3 into mp3 so that the file will be smaller while still keeping the video. ive tryd with dvd2avi and it gives me the audio file smaller but the vob still has the original audio with it is ther a way to merge the files thanks.
