This program really saved us. We needed a last-minute solution to turn .m2v files from Compressor into muxed files that our video server could handle. This program was easy and fast. Thanks! Note that this is the only task we needed, so I'm not familiar with other aspects of the program.
Great as far as it goes. But it seems unable to handle an mpeg2 (.mv2) file larger than 2GB. I have notified the developer.
Also, run the application from the top level of the folder "Applications", not from a subfolder. It may fail otherwise.
