There are a lot of free programs offered here, but here's the link to Directory Printer. hxxp://www.karenware.com/powertools/ptdirprn.asp If I'm not suppose to post this type of thing, please delete this post.  I just figured since its free and open source it would be ok. Thanks for the program, will try it out

Many times people go crazy and get conflicting codec and that causes the problem.
