i use Allok Video Joiner to join all my files
just line them up and set the quality yourself
1) Video applications do not always work with audio alone as the OP is using.
2) The OP has already found a solution. It was a Mac-specific tool whereas the one mention states:
System Requirements of Allok Video Joiner
* Windows 98/2000/ME/XP/2003 operating system.
3) "Set the quality" suggest it is recoding the file which is not necessary and results in quality loss.
