I have used a video camera that stored files on an internal HDD in the .MOD format. The software that came bundled with the camera included software to convert the .MOD files into a format for editing. That software was PowerDirector from CyberLink (http

/www.cyberlink.com/products/powerdirector-ultra/specs_en_US.html). It did a good job of converting the files.
Another option is to change the file extension from mod to mpg or .avi. I tried that and sometimes it worked but not always. If you want to try this I suggest you try it with one file and see if the file plays back as it should.
