[vdr] vdr-1.3.33, list of recordings is still empty

@Klaus

I have a nfs-mounted video-dir which is mounted after vdr is started (to realize very short boot times). One of the last commands in the startup script is a `touch .update` which used to work without problems.

In the latest version the list of recordings is still empty, even if I try to touch the file more then one time. :-(

But, a test with

`echo "LSTR" | nc localhost 2001`

(nc is the netcat-version of busybox) gives me a list of all recordings. Unfortunately this has no effect on the OSD-Listing.

How can I force a complete reload?
