Burning DVD using PowerProducer Gold

Hi, sorry to bother you guys. But i have recently downloaded some shows which was in .rmvb format. I want to convert it to mpeg in order to put on dvd. After the conversion i was able to put about 4 .mpeg into one DVD.

But when it was at the burning stage the program just crashes by itself. Like for this program it does not burn right away it organizes some stuff b4 burning, and during that organzing process it crashes.
