I am on the Internet for a very long time and experienced a lot of things when it was all about video conversion and also tested many applications, but nowadays there are some free solutions that simply beat the paid ones.
For example, you have VidCoder and Handbrake, one of the most popular CD/DVD video rippers and video encoders. Handbrake will convert your files to any file format you want (with or without installed codecs).
Of course, there is the professional one called Adobe Premiere Pro which is outstanding when it comes to video conversion and video production. You should try all of them.
