AE CS4 will not import m2t files unless they have a pek or cfa associated files

I have m2t files that contain these following files associated with the m2t files...

cfa, pek, mpgindex, xmp.

Using CS4 in WinXP (32bit).... m2t files are 1.33 30p 1440x1080 HD files captured from HV30. All files (both that render/import and do not render/import) were captured using Avid Liquid.

The files that have these associated files will open up with Premiere Pro and After Effects... but, an entire directory of m2t files that do not have these associated files (except xmp) will not open with any Adobe editing or compositing software.

These same m2t files (with or without the associated files - cfa pek mpgindex) will open and edit fine with Avid Liquid NLE... but without the cfa pek files, the m2t file in AE or PP will not open... instead, I get the dreaded media pending files.

My assumption is that Adobe would create these associated file when you import into AE or PP... but, for this one large directory of m2t files neither AE or PP will import but only shows the "media pending" gold window... and will not render in PP... and, do not contain (nor creates) the cfa pek mpgindex assoicated files.

Any solutions as to why a single directory of m2t group of files fails to import or render with PP or AE? Plus, why aren't the the typical pek cfa mpgindex files not present/created as in the other m2t files?

BTW, these same file are visible in Adobe Bridge and Windows media player.
