Version 0.61vdr-0.61

- When scrolling through a list it now moves a full page up or down when the
  cursor reaches the top or bottom of the menu (thanks to Heino Goldenstein!).
- Added missing '#include <sys/stat.h>' to recording.c.
- The video directory can now be defined with the command line option -v.
- There can now be more than one video directory (in case you have several
  disks).
- Fixed learning key codes for PC keyboard.
- New command line option '-l' to set the log level.
- Times in timers.conf are now always printed with 4 digits (leading '0').
- Slow forward/back mode (thanks to Guido Fiala!).
- The "Up" key in replay mode no longer restarts replay at the very beginning,
  but rather resumes normal replay mode after a "pause", "forward" or "backward"
  operation. Use the "Skip -60s" function repeatedly to go back to the beginning
  of the recording.
- Improved reaction on user input in fast/slow forward/back modes.
- No more upper limit for the value of 'Pnr'.
- Checking if the video card is really a DVB card.
- New SVDRP command UPDT to update an existing timer (or add a new one if it
  doesn't yet exist).
- New version of the 'epg2timers' tool (with a modified channel list).
- Bugfix in closing window in DEBUG_OSD mode.

 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.
-If you prefer a different location for your video files, you can change
-the value of 'BaseDir' in recording.c.
+If you prefer a different location for your video files, you can use
+the '-v' option to change that.
 
 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
+   /video2
+
+would be a setup with three directories. You can use more than one
+numeric digit, and the directories need not be directly under '/':
+
+   /mnt/MyVideos/vdr.00
+   /mnt/MyVideos/vdr.01
+   /mnt/MyVideos/vdr.02
+   ...
+   /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
