AnyDVD for sure, keep getting the updates as this allows you to burn anything.
I use Nero 7 for my burner though. New, good dvd players will have no trouble playing what you burn with Clone DVD2. Older, or cheap players may skip a little. I choose to use Nero Recode 2 for my burning; it is much slower (about 3 times as long from start to finish) but I have had perfect burns which will play on any device. I just use the advanced analysis feature on Nero (makes the file twice and checks against itself for jitters).
