Yes, combustion is probably one of the most under rated programs out there. It is really similar to the flint/flame units we use - and its a lot of fun. I strongly recommend it to anyone trying to do this sort of work.

Re CCE, to anyone out there playing with it - it does take a lot of playing to get the best results, you really notice it's advantage on scenes that cause problems, but like a lot of things an untrained eye will really only see the difference when displayed side by side with other encoders results.

Check out doom9 or other sites for advanced CCE techniques.
