No.  Thumbnails are only generated upon recording creation, transcoding, 
cutlist editing, or bookmark placement.  The reason it takes so long is 
because the backend protocol command QUERY_RECORDINGS does not support 
paging.  The backend has to process all 3094 programs, and send the data 
to the frontend.
