CBR is Constant Bit Rate -- For example, if your movie has a 1 minute gap where everything is just black, or there is very low motion, than it will still encode that portion of the movie at 300kbps or whatever you chose.<br><br>VBR is Variable Bit Rate -- For example, during that one minute gap, it will encode at a lower bitrate, because a higher bitrate is not needed.<br><br>if you encoded a movie in both VBR and than CBR, the VBR movie would be smaller, yet have the same quality level as CBR.<br><br>Also, vts_02_1 or vts_02_01 are standard files in NTSC DVD's. They represent the movie itself.. vts_01_01 is the intro, and vts_03_01 is the extra stuff.
