On my system, 208 recordings takes 7 seconds (and almost all of that is
browser page layout time).

Yep.  If you're saying that the *.mpg.png files in the MythWeb
data/cache directory are recreated, you've probably got mixed versions
of code (i.e. bad SVN update, bad install, ...)

cache]$ ls *.mpg.png
ls: *.mpg.png: No such file or directory

There shouldn't be /any/ *.mpg.png files in MythWeb (they're the
previews used by mythfrontend(s) not by MythWeb).

If you're saying that the *.mpg.png files on the backend's recordings
directory are being recreated, it means that the date of the PNG files
is < the "last modified date" for the recording (in the database).  That
generally happens because of bad permissions in the recordings
directory--and the fact that it happens every time just reinforces the
theory; it's unable to update the preview timestamps to the current
time.  I have *.mpg.png files in the recordings directory going back to
Nov 18, 2006--my oldest recording.
