The formats below, almost without exception, are those that cause the greatest amount of confusion for beginers. Please bear in mind that almost all are not codecs, but file systems mistaken for codecs. Check the MPG page for information on the codec varients most commonly stored in the following file types.

BIN
Bin files are a file type created for burning to CD. They allow the placement of multiple files to fixed points on a cd's surface, thereby getting around some copy protection schemes. No clue as to why they would be used for multimedia, but they are. There's an great program I use all the time called Vcd Gear, with it's GUI, that makes short work of converting bin to mpg. no Test
VCDGear
DAT
 not a codec, DAT is a form of mpeg1 used in VCD's. If you put a VCD into the computer, look at it under Explorer (or what ever you use ). In the folder  Mpegav  you should see a file called Music01.dat or a group of smaller files called Music01.dat, Music02.dat, etc. Each one is a complete mpg1 file with extra encoding for the VCD standard. If you moved the file to your hard drive, then just add ".mpg" to the name (WantaWatchThisMovie.dat.mpg) it should play. Again, VCDGear (use the GUI ! is a prefect free converter tool for making dat files into mpg1 files . no Test

DVD
Sometimes a file will be listed as "DVD mpg". When listed this way, most often all the poster is doing is informing you that the file is an mpg2 file 720x480(ntsc) or 720x576(pal). running at 29.75 fps. Otherwise, he's posted a Vob file. If the ending is Mp2, or Mpg2 (as well as just plain mpg ), all you need to play this file is an mpeg2 codec. If you use Windows and don't have one, click the link to the right. If you prefer a seperate MPG2 players, including this one at digital-digest.com (Look for the Elecard shareware player). no Test

ISO
An ISO file is a cd image file used to make a CD.  It was designed to be burned to a CD with a program that's capable of reading ISOs like Easy CD Creator 4. Or, you can use a tool like ISOBuster (again, make sure you pick up the GUI interface ), which will allow you to recreate the CD on your hard drive.
From YaHosna comes this info:
It's possible to "mount" an iso file under windows or Linux with a driver you need to install that will recocognize an iso as a CD-ROM. It should then behave like a VCD or SVCD or ISO9660, or Joliet or whatever.  Nero(.com), has such a driver available.  I think it is included with Nero 5.5 and possibly separately, and maybe free(?).

VCD 
Sometimes a file will be listed as "Super VCD mpg"or "SVCD". When listed this way, the poster is informing you that the file is an mpg2 file 4800x480(ntsc) or 480x576(pal). If you don't have the MPG2 codec, all windows users need to do is to add it, or use another mpg2 player (see DVD). Test
Mpg2 codec
VCD
Sometimes a file will be listed as "VCD mpg". When listed this way, the poster is informing you that the file is an mpg1 file 352x240(ntsc) or 352x288(pal). The file should play fine. If you're missing the codec, you might need to try and reload the media player. Often however, the file comes out as one of the others listed here, like a Bin / cue file. For that, get VcdGear. Test

Vob
 Vob files are a form of Mpeg2 video track laid down on DVD's. Becoming more common as burnable Dvd's are reaching the market. There are several tools are avialable to convert this form of file back to mpg2, and can be found at VCDhelper.com along with the instructions on how to do it. no Test

Coming soon will be a section on DV codecs - almost all a Motion Picture Group standard 4 (MPEG4) varient from QT. Because of the bandwidth involved, there will be no tests available.
