ImageReady CS Help

I just recently formatted my computer and re-installed PhotoShop 8.0 CS with ImageReady. I use the Imageready all the time making .GIFs.

I have a video converter to convert the files/videos to .mpeg2 format so Imageready would accept/read it as a valid file type. Well after reinstallation it will not read .mpeg2, I tried also .mpeg1, .avi, .wmv just incase.

So my question is, what did I do before to be able to have Imageready be able to read the .meg2 files so I could make the .GIFs???

All advice is welcome.

Thank You and Have a Good Day.
