Now that I've found a way to record in surround sound I'd like to keep surround intact while editing the files. Features I need include trimming, appending, and adding narration to paused frames.
Ease of use and cost (less than $100) are my primary concerns. There is no need for special effects or advanced transitions.
So far I've tried Windows Movie Maker and Vegas Movie Studio Platinum. The latter looks promising, but it won't detect the audio in my 5.1 channel video files. (Windows Media Player does play the files back in surround sound.)
EDIT: For reference, Windows lists the audio in the files as 4608kbps, 6 channel, and 48kHz.
