Mike/William, Thanks for the replies. After reading this reply I realize I must have been asleep at the wheel when I wrote my original question, because I left out an important detail. I said I was using mythvideo, which is partially true, because sometimes I use it (with the Internal player). I really have the volume problem when I play the videos over NFS using an MVP1000 and the mvpmc software. I apologize for the major oversight. So my problem is the volume of the MPEG videos themselves. OR, mvpmc/mvp1000 is the problem. Maybe I'll try to play a video on my computer and also play a DVD and see if the volume levels are similar. Maybe that would at least give me an unscientific starting point at where the problem really lies. Thanks, James
