Can´t play a vcd avseq01.dat in my dvd

if it is a video cd - it can be opened from Windows Media Player, Winamp, Nero Vision and many other video players available on net. By inserting the CD inside, windows will open a dialog box asking you, with which program you want to open it - just select the program and press ok.

But for playing any video cd manually, if it is a VCD - open CDROM from my computer - Open "MPEGAV'" folder - and play any file with extension ".dat"

For playing Video DVD - Open CDROM from My Computer - Open "Video_TS" folder - Play any file which is having extension ".BUF".

Please be more specific about what you need help with. Are you looking for a codec for a media playing software that you already have or are you looking for software to play DVD's, VCD's and other media files on your computer?
If you are looking for a way to play DVD's, VCD's and other media files on your computer and dont want to pay a dime for it,.. download VLC Media Player by VideoLAN Here

Search freeware on Google and find an AVI codec file to download and install. Then reboot and try again.

windows media players seem to have a prob. with having all the codec you might need to play a movie. ...even after you install more codec. ....go to the site for VLC media player and download it and you it as a default player. ....vlc media player has all the codec's in it that you would ever come accross. ....works great for me and has never found a movie it could not play

There are three ways to create a Video CD (VCD) that contains your photo stories:
You can obtain Microsoft Plus! Digital Media Edition and view the Photo Story 3-authored WMV file in Photo Story 2 by going to Play your story or create a video CD of your story and then create a VCD.using the Photo Story 2 Video CD-burning feature.
• You can obtain Microsoft Digital Image Suite 10 or above and view the Photo Story 3-authored WMV file in the Photo Story that comes with the Digital Image Library and save and burn to VCD.
• You can obtain VCD-authoring products that work with Photo Story files, such as MyDVD by Sonic Solutions or InstantCD\DVD by Pinnacle Systems. You can use these software to convert the Windows Media video (WMV) files into files that can be copied to a DVD and played in a DVD player.
Note: VCD and DVD-authoring software is not included with Photo Story 3.

try reinstalling ur burning software....

By default, Windows does not include a DVD decoder (which is what you need to watch DVDs).
If you are using WMP10: http://www.microsoft.com/windows/windowsmedia/player/plugins.aspx
If you are using WMP11:

Install the codec and you will be able to watch DVDs!

this problem is occur when your computer does not have proper dll file to handle this media type u can use any free media player software or upgrade ur media player using microsoft update if problem is steel then try using vcd cutter software

I guess that this file is from a VCD? If you just burn that file onto a CD as a data CD it should play in your DVD player. The AVSEQ01.dat file is already a (S)VCD file. It is in MPEG format and should be playable on a DVD player as is. Alternatively you can import the file you want to burn into nero vision. Once it is imported then choose to export the file as an MPEG file or burn direct to DVD. Please update the question & let us know if the information given was useful to you - Good Luck!
