Raymo,
Which MOV conversion software did you use?
I'm not experienced in MOV files but this one looks promising
http://www.tucows.com/preview/606789/Convert-MOV-To-AVI
then there was
http://download.cnet.com/Free-AVI-to...-75891858.html
to hopefully allow the AVI you created to be returned to a MOV.
HTH
