Missing CODEC

I am trying to work on one of my old video projects, now that I am somewhat "back".
When I open an old project in PRE10 (my latest version) the Media files come in OK, but the timeline is blank, obviously losing all my work.
If I load up PRE7 which was probably used to create the project, it all looks OK but when I try to create a DVD I get an error popup that it needs to load a component (CODEC?) for MPEG2 and gives me a URL at Adobe to get a code. Of course, the URL is old and 404.
I am thinking I need one of the global CODEC packages installed, but don't remember which one we used to recommend. Can someone refresh my memory or provide any other insight to get PRE7 running?
Thanks much...
