HTMLPurifier stripping out tags

Members can no longer embed mp3s and maybe even videos.  I tested it on the 7.1 Final test site and it is working there.  So something happened to change what/how HTMLPurifier is working.  It is not TinyMCE, TinyMCE is allowing the content; it is being removed on saving.

I am not exactly sure when it started doing this; the only thing I can think of is that a module installation caused this; however, I have try replicating it on the test sites, installing modules to see if it breaks but without luck.

Any ideas appreciated on how to track and fix this little problem.

I uploaded the htmlpurifier directory from the 7.1F download.  No change.  Something is causing embeds to be stripped of their code.  I can post the exact same embed on a clean install Dolphin 7.1 Final but not on my site.  Has anyone installed any of the modules from the market and had this to happen?

And I have tried to install some of the mods on the test site to see if it would break it on the test site.  No such luck.

OK, I just posted a blog without any problem with the same code.  It might just be only comments that is removing the code when I post.
