Thanks for the reply. No, only in the backend's recording directory.

If you're saying that the *.mpg.png files on the backend's recordings

The recordings directory has rwxrwxrwx.

I started looking at what actually happens, and now I am not sure if it is
really recreating all the files or if it is just updating their timestamps
to current time. I tried deleting all the mpg.png files and it takes exactly
as long, as when the files already exist, to create new files when I load
the Mythweb recordings page. I would imagine that if it is only updating the
timestamps it wouldn't take as long as creating new files. Or maybe my
backend is simply slow (dual athlon XP-M Barton at 800 MHz, 1GB RAM,
recordings directory on 3 IDE drives with xfs on LVM about 600GB).

Anyway, Unixes have no creation time stamp, so I have a hard time figuring
out if the files are actually recreated, or only updated.

A file in the recordings directory:

ls -lu  2010_20070219152500.mpg.png
Aug  3 23:41        (the access time is actually when it was created)
ls -lc  2010_20070219152500.mpg.png
Aug  3 23:44        (change time changes when accessing Mythweb recordings
page)
ls -l  2010_20070219152500.mpg.png
Aug  3 23:44        (modify time changes when accessing Mythweb recordings
page)

After accessing Mythweb recordings page once more:

ls -lu  2010_20070219152500.mpg.png
Aug  3 23:41
ls -lc  2010_20070219152500.mpg.png
Aug  4 00:06
ls -l  2010_20070219152500.mpg.png
Aug  4 00:06
