How do I turn TS files into something I can copy into my video files?

I burned a DVD and mistakenly deleted the file that it copied. Now I cannot put the file from the DVD back into the computer. I have Windows XP and us Windows Movie Maker to edite the movie.

I get a message somewhat like..“movie maker cannot open a TS file." What is TS anyway?
Thanks

WMM supports wmv and avi video. In VIDEO_TS, there are .vob files.
You need to convert vob to wmv or avi, before importing into WMM.

WMV Video Converter for mac, DVD to WMV Ripper.
