[vdr] small patch for vdr.c: continue even with read-only video directory

[Peter Münster]

Hi Klaus,

Could you please delete line 577 from vdr.c or do something similar to
let vdr continue even with read-only video directory?

vdr runs fine with this patch on my system, and it's important for me,
that vdr cannot write anything to the video directory.
(see also http://pmrb.free.fr/vdr/)

Here a small patch:

--8<---------------cut here---------------start------------->8---
--- vdr.c.orig	2013-03-09 21:13:57.846826771 +0100
+++ vdr.c	2013-03-09 21:16:33.503521762 +0100
@@ -574,7 +574,6 @@
 
   if (!DirectoryOk(VideoDirectory, true)) {
      fprintf(stderr, "vdr: can't access video directory %s\n", VideoDirectory);
-     return 2;
      }
 
   // Daemon mode:
--8<---------------cut here---------------end--------------->8---

If you prefer, I can write a better patch: stop if not readable, warn if
not writable.

TIA,
