The Bloodhound Gang one is fine for me, so though I don't have the other two I'd guess it's a problem at your end.
And incidentally, I think I've had that problem before as well - but it used to do it with ALL mpg files. I had to format my computer to fix that, but if you're having a problem only with a few vids I'd suggest firstly just downloading them again (from a different server perhaps) and trying again.
