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
