In this discussion there was reference to converting my files using a program called Freemaker video converter, I did that and only one DVD converted properly and now I'm left with no software to do this.  I did try to open DVD in windows media player and hope that would work, but it does not read my disc.  I have windows 8.1 operating system and since this is a new computer I'm hesitant to just start downloading programs/software for this OS without knowing they will work.
