playing .dat movies under linux

I have on a CD a .dat movie. It is most probably in an MPEG format, as my mp3 CD Player is able to play the sound. Now, under Windows 2000 i can play the movie. Windows Media Player and DivX Player had no problems in reading it. Under Mandrake 10.1 Official it seems impossible to play it. Mplayer, Totem, Kaffeine were all unable to run the file.

I am thinking whether it is possible to somehow edit some Mplayer config file (codecs or other) so that Mplayer interpret a .dat file as being in MPEG format.

Anyone who could indicate me how to do it?

I can't help you to do what you are asking for but you should know that about .DAT files:

The ~600 MB file visible on the first track of the mounted VCD is not a real file! It is a so called ISO gateway, created to allow Windows to handle such tracks (Windows does not allow raw device access to applications at all). Under Linux you cannot copy or play such files (they contain garbage). Under Windows it is possible as its iso9660 driver emulates the raw reading of tracks in this file. To play a .DAT file you need the kernel driver which can be found in the Linux version of PowerDVD. It has a modified iso9660 filesystem (vcdfs/isofs-2.4.X.o) driver, which is able to emulate the raw tracks through this shadow .DAT file. If you mount the disc using their driver, you can copy and even play .DAT files with mplayer. But it will not work with the standard iso9660 driver of the Linux kernel! Use the -vcd option instead. Alternatives for VCD copying are the new cdfs kernel driver (not part of the official kernel) that shows CD sessions as image files and cdrdao, a bit-by-bit CD grabbing/copying application.

Thank you for the information. It helped me out. The problem was that i did not realize that my CD was a Video CD. Neither did i have any idea how to play a VCD under Linux (mplayer vcd://2 /dev/hdc).

I would still like to know whether there is a location where to download powerdvd from.

Why have I successfully copied .DAT files off of a CD, renamed them to *.mpg and end up with a viewable file if that is the case?
