Hate this software.

Compress 1-2 hours weekly with this and if there were ANY other program that could compress large files with the codec I use I would buy those programs in a heartbeat. The interface is clunky, confusing, and busy. Altogether the most buggy compresson software I know of but it could be so wonderful, just wish it had some developers who would dig in and make it usable.
