Hi Klaus,

I've tracked down a nasty "Error while accessing recording!" / "Fehler 
beim Ansprechen der Aufzeichnung!" OSD message, occurring sometimes when 
deleting recordings in sub folders. This only occurs if the deleted file 
was the first one that was added to that sub folder - and maybe some 
other conditions.

Thats what imho happens:
-The file gets removed from OSD menu, Recordings list and disk.
-cMenuRecordings::ProcessKey(kNone) triggers a Set() update of the 
current menu.
-After that, ProcessKey(kNone) of the main recordings menu triggers a 
second Set() for the main recordings menu.
-The second Set() call tries to remember the currently selected menu 
entry (the currently open sub-menu) by calling GetRecording() for it.
-GetRecording tries to find the matching recording by comparing file names.
-Folders use the file name of one of their recordings as dummy, and, by 
bad luck, this one is the one that was just deleted.
-GetRecordings fails and throws the error.

Something similar should happen if the currently selected menu item gets 
externally deleted, but thats less likely.
