I have used Fast DVD Copy since version 2. I have used it on G4s, G5s, and Intel Macs from macbook to minitower over the last few years. I have used it with the internal Mac supplied superdrives and both external and internal aftermarket superdrives from Sanyo and yamaha. I have NEVER had a failed burn. I have had a failed read/compresion due to a new copy protection scheme which the free updates fix, but never have i had a wasted DVD inhundreds of burns. If you want free get mactheripper. If you want flexible, easy, offering the option of single or dual layer burn, and one click which still offers you the option to save the TS file like i do........... then you want this software. Users waste DVDr's, not Fast DVD Copy....... it is the best at what it does.
