  3. Great explanation! Just what i need it. The VLC Player goes really well to me, i could open the files with no problem! Thanks guys!!

  4. Question: I have a an old dvd of home videos with those three files. Can I copy them to a flashdrive to give and share with relatives? I’ve found a recording studio that will do it for $80, but there must be some software out there that I could do it myself. Is there an issue with copying it onto a flashdrive? I tried to put it on my nephew’s Apple and only the video would play – not the audio. Is the problem in the copying or in the playing?
