look at the filename. it's not an "emm pee THREE", it's an "emm pee  
FOUR". that means it's GOTTA be better, doesn't it? hehehe...

but seriously.

i'm not sure what you mean by "smooth". two things come to mind.

the first is audio quality. the audio in an MP3 file is compressed  
using the MP3 codec. the audio in an MP4 file can technically be one  
of several different codecs, but this particular file uses AAC  
compression rather than MP3, which generally sounds a little bit  
better than MP3 (to me, 128K AAC files sound as good as 160K MP3 files.)

the other thing which comes to mind has to do with buffering... most  
browsers, when they start to play a video, will download part of the  
file before starting to play it, in the hopes that the download speed  
will be able to keep up with how quickly the video is playing. maybe  
your browser (or whatever video-playing plug-in it uses) does better  
buffering for video files than it does for MP3 files?

otherwise, please explain what you mean by "smooth". what specifically  
is different between the two?
