That's the normal amount of time required to generate a thumbnail, but...

If these "new recordings" are still in progress, then what you're seeing 
is completely normal--it's generating a thumbnail on demand because you 
scrolled over the recording and mythfrontend requested a thumbnail.

If, however, the "new recordings" are finished recording and you're 
using -fixes the fact that it actually needd to generate a thumbnail is 
the problem.  Myth automatically generates a thumbnail image for every 
recording once the commflag job completes (or if commflagging is 
disabled, once the recording completes).  Then, it only regenerates the 
thumbnail when something about the recording changes.  This usually 
happens when something messes with the DB after the recording finished 
or something messes with the file after a recording finishes (such as a 
user job).  The whole purpose of automatically generating these 
thumbnails is to prevent this slow-down in scrolling through the Watch 
Recordings list.

If you're using trunk, however, it's all because you're using a work in 
progress.  (I.e. there are known issues with displaying previews in 
trunk with certain system configurations.)
