How do I use .m4v video files?

I build a few free sites and today one of the Sponsors I promote released some new content videos in .m4v format. I must be showing my age, as I didn’t know what they were, and nothing on my computer would play them. I googled .m4v and it said they are for use on an Ipod. Can somone enlighten me … how can I use these when I build free sites to promote the Sponsor site? If they were .wmv my surfers could click on them and watch online, but these .m4v don’t seem to do that. Anyone able to help?

try associating them with your quicktime player - they play fine in mine.
