Download VLC, open it, go to File->Open and then find your Video_TS file and open it and you should find it opens up at least something. To load only the movie you want, convert the largest size VOB file in the video folder using Handbrake and make it a .mp4 file (and make the size 320 x 240 if you want to play it on an iPod--or just drag the larger screen file to iTunes and select the movie and go to Advanced->Convert Selection for iPod and wait a few hours until it converts it) and you will be able to simply play it in QuickTime.
