I recently had old Super 8mm films transferred to a DVD.   Each reel of film plays as a chapter and the Dvd plays fine in Windows Media Player.  When I downloaded it to my videos file it was split into two files - VTS_01_1.VOB and VTA_01_2.VOB.  I imported both files into Movie Maker 6.  I have no problem editing the first of the two files but when I try to play the second, the preview pane is black even though the time indicator moves.  I have followed other suggestions such as changing the media type, compatibility etc. but it still won't play.  Does anyone know how to solve this please?
