What I mean is that in 0.24, there is no mechanism to programmatically
trigger a scan.  The only scanner built into MythTV is in the MythVideo
plugin, and can only be accessed with a keyboard or remote through the on
screen menu.  In 0.25, the scanner has been moved to a shared library, and
is now accessible to the backend through a backend protocol call.  All you
have to do is connect to the backend and tell it to scan.  This can be done
as easily as:

In 0.21-0.24, JAMU filled that role.  In 0.25, mythbackend will do it
internally with the above script.

Are you scanning from the combined FE/BE, or from a remote FE?  Are you
using Storage Groups (set in mythtv-setup) or the old folder definitions
(set in frontend setup)?  Is this content on something like NTFS, or is it
on a native Linux filesystem?
