My Video Files has changed their Format

I reinstalled my system files on my PC which involved formating C:\ drive. I saved all my video files (mostly mpegs) to external hard drive. For some weird reason they have changed format into something which can't be played. One of them does not even have a format.

How can I fix this?

Are you running XP or Vista? You need to get to Folder Options in amy Windows Explorer window so that you can show File Extensions. For Vista this is Organise, Folder and Search Options, View Tab and untick Hide File Extensions for Known File Types. For XP you can access Folder Options from any Explorer Window under View (I think).

If you then use Explorer on your external drive you will then see the file extensions of your video files and can see if they are mpeg. If they are you have a File Association problem and you just need to right click on one of them and alter the Open With command to the one that you normally use for viewing your movie files.

If they really have changed their extension to something other than mpg you can always try renaming one of them with the mpg extension and see if it plays.

I am running XP. Renaming and opening with a different media player does not make much difference. Other than that I am no getting the sound and a message saying 'downloading codec error'.

BTW these videos played perfectly before.

First the no sound and codec problem... have you checked the sound device under Device Manager to see if you have a yellow exclamation mark? And if so have you tried to update the sound driver?

Second when you looked at the file extension what was it?

The sound is OK! its the video that I am not receiving and I changed the extension to mpeg.

You could download G spot Yes Gspot its free and should identify the format and what codecs it needs

Thanks eedcam I ran G spot and it identified the following missing codacs on two of the films:
4CC - xvid, Name - XviD
and on one of the other films
4CC - H264, Name - ITU H.26n

I expect that all the other films will be similar, so where exactly can I obtain these codecs.
