 All recordings are written into directories below "/video". Please
 make sure this directory exists, and that the user who runs the 'vdr'
 program has read and write access to that directory.

 Note that the file system need not be 64-bit proof, since the 'vdr'
 program splits video files into chunks of about 1GB. You should use
 a disk with several gigabytes of free space. One GB can store roughly
 half an hour of video data.
 
+If you have more than one disk and don't want to combine them to form
+one large logical volume, you can set up several video directories as
+mount points for these disks. All of these directories must have the
+same basic name and must end with a numeric part, which starts at 0 for
+the main directory and has increasing values for the rest of the
+directories. For example

+   /video0
+   /video1

+numeric digit, and the directories need not be directly under '/':

+   ...
+   /mnt/MyVideos/vdr.11

+would set up twelve disks (wow, what a machine that would be!).
+
+To use such a multi directory setup, you need to add the '-v' option
+with the name of the basic directory when running 'vdr':

+   vdr -v /video0
