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.
