Another Sony user here...
I use the Sony Vegas Movie Studio HD Platinum 10 Production Suite -- it comes with the Sound Forge Studio version, and you can pick it up on Amazon for under $50 (they're up to V12 now, but 10 works fine for me).
You can do movies, music, burn DVDs, Cds, Blu-Rays -- just about anything.
Does require a bit of a learning curve, but it comes with a tutorial DVD, and built in how to's.
