I use, magix movies edit pro, demo version, my previous version, magic movies 3 on cd and dvd worked well with vista home premium but didn't recognize my dvd drive in windows 7 so trying this version, the pc I have is 1 week old, windows movie maker does see the dvd drive and also ashampoo burning studio. how can I make the drive appear in this program, I did when 1st trying see that there is a missing dll but the message only appeared once and disappeared very quickly, all help and advice gratefully received because all movies are of my granddaughter and I send copies to family not only the other end of the country but also in the usa
