conver mod files to media player

How do I convert mod files that are backedup on my hd from my jvc hdd camcorder??

Depends on what you want to convert it to... Are you on a PC or on a Mac? Are you able to play the files at all? If so, what media player are you using?

This could help if the software you’re using to convert can’t read the mod files. You could also try renaming them to mpg or m2v.
