Can't copy files in *.dat form VCD

[Parameshwara Bhat]

Hello List,

I have played files with extensions *.dat with both 'xine' and 
'mplayer'.The vcd of the film "Unfaithful" has three files in the 'MPEG' 
folder,Music01.dat,Music02.dat,Music03.dat.I played this file from the cd 
in Windows Media player as well as SiS mmplayer.Now I copied those files 
to a separate directory and later opened them using both Mplayer and Xine.

Xine even has a file filter for *.dat type of files.Mplayer like its 
namesake Mediaplayer doesn't automatically filter the files but once 
selected using filter "all files",it plays it anyway.But both these 
programs fail to run the same files from the CD when tried with Play 
File.(They can very well play the VCD containing these files)whereas if 
these files are copied to harddisk they can play it.

Curiously within Linux,these files cannot be copied off CD.But,once in 
Windows,you can copy them and store them.Both Xine and Mplayer play them 
now once they are stored like this. And that's how VCDs are kept on the 
harddisk by all my friends here.

This is curious.Could anybody shed more light?
