I am using Limewire and Ares with a Windows XP system. I have CloneDVD program and a dvd Decryptor program, but can't quite figure out how to burn my Limewire and Ares MPEG downloads to dvd.

What movies are these?

Since Ares is designed to "share" copyrighted music material and Limewire is designed to "share" copyrighted video material, you're not going to get assistance in pirating activities.

Meanwhile, those communities surely have people that don't care and will give you whatever help you need.
