DVD Copyright:It is against the law to reproduce copyrighted material for the purpose of selling it to third parties. Some country's' laws only allows for you to make one backup copy of any software or media for personal and archival purposes, which is the only intended use for Apollo DVD Copy. This program is not meant for those who intend on breaking copyright laws. In no way will we be held responsible if you do. Any other illegal use of this software is strictly prohibited.

D5 and D9:There are 4 standard formats. D10 and D18 are not as common.
A DVD-5 (single sided) DVD-Video disc will hold nominally 133 minutes of high quality MPEG-2 encoded video, together with three surround-sound audio channels and four subtitle channels. (Without video compression one DVD-5 disc would hold only about 3 minutes of video). A DVD-9 (dual layer) disc increases the playing time to 240 minutes of continuous video.
A DVD-10 (double sided) disc will hold a nominal 133 minutes on each side (ie 266 minutes in all), but the disc needs to be turned over to play the other side. A DVD-18 (dual layer, doubled sided) disc can hold 240 minutes on each side and the disc also needs to be turned over to play the other side. Most DVD is D9 or D5 format. Our software can clone D9 to just ONE DVDr/rw disc (D5 format) without evident losing.
