I haven't burned any DVDs yet, but my brother in law does. I am not sure what software he uses and I pass along some information that he gave me. He video taped my daughter's wedding & reception and then burned it to DVD for them. He said the amount of computer memory and the speed of the hard drive made the biggest difference in how long it would take to burn. I think the final DVD was only about 35 to 45 minutes long and he said that it took about 3 to 4 hours to burn the first one. Then he would copy it for additional copies. He said that he started by using an external/USB2 hard drive that was dedicated to video processing and the time it took was more than double what it was from the internal hard drive. Also make sure you keep the drive clean and defragmented.
