detecting ".dat" extention as "plain text document"

Postby jan_valjean on Fri Mar 16, 2007 7:39 am

Hi,

How can I solve this odd detection by my system? When I attempt to open a .dat file (video CDs) this is what I get from, for example, MPlayer:

"The filename "avseq01.dat" indicates that this file is of type "MPEG video". The contents of the file indicate that the file is of type "plain text document". If you open this file, the file might present a security risk to your system."

Thank you in advance.

Please could anyone help me with this problem? Mint detects ".dat" files as "plain text document", and I can't open and watch video CDs. I know the problem is because of word processors as well as text editors of all kind, but simply I don't know what to do, how to prevent such editors from involving ".dat" files.

You have to open the Video CD as "Video CD" and not the single files on it. If you burnt the Video CD correctly then it should play.

Thank you. With MPlayer I have tried this way, too. And below is the error I get. What is it and what am I to do in order to fix it?

Thank you again.

Fatal Error

Error opening/initializing the selected video_out (-vo) device.

That's something completely else. In theory every video medium should fail then in your case, not just Video CD's.

Go into the "Preferences" menu of MPlayer and check the "Video" output settings. Depending on your graphics card and driver that you use for it not all options there might work equally well. So you should pick another output method and try again.

What PC and what graphics card do you have?

Thank you scorp123.

* Intel 945 G/GZ Express Integrated Graphics Controller

* The related packages for the drivers, xserver-xorg-video-i810 and xserver-xorg-video-intel, are installed.

* In MPlayer's preferences available drivers for video appear as: xmga,xv, x11, gl, gl2, dxr3, xvidix, xvmc

* And in the tab "Codecs&demuxer", available video codec families are:

Null video decoder
FFmpeg's libavcodec

Something wrong or missing?
