Below is a cut and paste of the current contents of the thread at the Adobe forum at http://www.adobeforums.com/webx/.59b6a7fa/0 The response in message 1 indicates the need to install additional system wide available codecs: so this does seem to be generically the same problem as prior versions of PSE not having thumbnails for MPEG2 files unless the customer installed additional codecs . However for AVCHD, where would a person obtain such a codec?
PSE7/PRE7 and AVCHD

Hi All,
The main reason I upgraded to these was that I read the bundle supported this format that my video camera writes. It looks like it is only PRE7 that supports it though. However, if you add files to a project in PRE7 they do get added to the Organiser in PSE7 but you don't see the thumbnail and can't play them there. You can tag them in either program. I'm quite disappointed that PSE7 itself can't deal with it, the tagging is a bit easier there.
Stephen.

I think the some codecs need to be separately installed to see the thumbnails of the files in the PSE.
