Is there a way to pipe an "avi" file to mplayer
standard input so that the file plays to completion?
------------------------------------------------------------

When I use mplayer to play the file in question everything works. 

However, when I try to pipe the file to mplayer, it plays 
correctly (for a while) and then quits with End of file. 

This is a big avi file (5.7 GB) which has been "merged"
from smaller avi files.

Is it possible that this behavior has something to do with
the length of the avi file? The file resulted from merging
several smaller avi files (I used a number of different
programs including avimerge with similar results)?

Does mplayer need to seek backwards at some point in a long file?
If so can that be suppressed?

--TIA
