My family made me a video of old and new family memories, the players I have don't work. I have Realplayer basic and windows media player. I need something they will play dat. files. Thanks Queen

Windows Media Player will play DAT files.

You have to select the file and then hit the "open with..." command and select Windows Media Player.

Thats what I thought, but... it won't open, keeps trying but no go. Is there something in xp I need to adjust or turn off.

Realplayer Basic!!! yowsers!!! Grab the spyware detector!!! we're going hunting

Tru the built in AVI previewer in Kazaa Lite.

pardon my ignorance, odie, but how, I found no such option in Kazaa lite

It should be in the start menu Queen.

i've never gotten that to work. install some codec pack, like nimo or k-lite, and stuff will run smoothly. it's even got an own dvd-decoder now, so you won't have to buy that either

nimo [download the lite version, pro is for advanced users and rippers]

k-lite [download the basic version. same reason as above]

Thanks to Pain and Odie, I can watch my movie. Thank guys, and everbody else for you help.

Odd, mine worked like a charm....

was probably wmp's associates that was messed up. and probably real's fault. what a piece of crap-ware

Quicktime did it

DAT files are best viewed with a DVD player. try PowerDVD or WinDVD
