-  <dt>Cache channel icons:
-  <dd>
-  Enable the caching of channel icons. This will cause TVH to download channel
-  icons locally, and then when requested via HTSP clients the URL for the icon
-  (or logo) will be retrieved from the TVH web server rather than fetched each
-  time by the HTSP client.
-  This REQUIRES the TVH server IP address field to also be populated

+ Icon caching - this will cache any channel icons or other images (such as
+ EPG metadata). These will then be served from the local webserver, this
+ can be useful for multi-client systems and generally to reduce hits on
+ upstream providers.

+  <dt>Enabled
+  <dd>
+  Select whether or not to enable caching. Note: even with this disabled
+  you can still specify local (file://) icons and these will be served by
