Since your tapes are only 1 hour, you will have enough space on your DVD to use the “DVD best quality 90 min” and either 4:3 or 16:9 which ever matches your source tapes. That is what I use. Obviously if you have a source tape that is longer than 90 min, you would use 150 min or higher. The higher the time (90, 150 min) then the lower your bit rate will be and the lower your final quality will be. I hope this helped!
