This patch works OK for the cutting process. I have not tested it 
for a normal recording, but I don't see anything what is against 
it.

But I found another thing what could lead to a problem. VDR always 
decides to delete the oldest recording if you have all other parameters 
at the same value (lifetime...). But if you try to cut your oldest 
recording the new directory will get the same name only with a "%" 
in front of the toplevel directory for this new structure. This means 
that VDR will find this one as the next one which has to be deleted.
And it does. You can imagine the problem?

Here is a part of my message file:
