Lightroom: 3.4 unable to create slideshow video with soundtrack.
I created a voice over for my slide show so that I can send the file to relatives to watch.
Voice over created with as an iPod voice memo. That created a .wav file which LR does not support. Annoying, but fair enough. Next step was to create a .m4a file which LR claims to support. That runs within LR, but crashes when I attempt to create a video file (the intended recipients do not have LR).
Error text:

Third step was to try a .mp3 file.
That comes up with an exclamation sign beside it, and will not run withing LR. It also crashes the "create a video" subroutine within LR. Different error to above. I could find no explanation of what the exclamation means. I tried the help, clicking, double clicking and right clicking.
Both conversions were from the original .wav file by WavePad Sound Editor v4.5.1 using default options in the SaveAs dialog box
