That's because it first logs that it is going to record to that directory,
and then initiates creating the directories as necessary.

Well, here we go: the directory containing the ':' could not be created.
This would indicate that you are using a VFAT file system, but haven't
built VDR with VFAT=1.

Here's the problem! The cRecorder itself does check whether MakeDirs() returns
'true', but in menu.c, line 2999, the 'summary' is written anyway.

Please try the following modification to menu.c, which puts the creation of
the directories _before_ setting up the cRecorder:

Line numbers may be somewhat off, but it shouldn't be too hard
to insert these two lines manually.

Let me know if this helps.

Klaus
