Do you guys know any good applications that I could use to convert it? Im trying to compile some family videos through experimenting on iDVD and iMovie.

If you have some .dat files from VideoCD or some other materials, they're just MPEG1. Change the file extension to .mpg and you can read/edit them with almost any video editing software ever created. MPEG1 is one of the oldest video compression formats available. The standard specs are 352x288 at 30 fps, but the more common usage is 320x240 @ 30 fps.

Hope this helps...

Wow. I did not know that. Thanks I will try it ASAP.

Ok. I changed it to .mpg and it worked. Now I need to find a way to convert it to .avi or .mov file in order for it to work on the current iDVD since it does not support the file. I have tried your specific settings but the problem being is that the sound is not there. where have I gone wrong? I have been playing around with QT pro 7 btw and have been trying to export it so that it works for iMovie or iDVD.
