vdr/menu.c
Klaus Schmidinger 76c331181a Version 0.63 
- The new "Setup" menu allows the user to configure several parameters to his/her
  personal taste (see MANUAL for details).
- Workaround for a driver timing problem in cDvbApi::Cmd(), which sometimes caused
  the OSD to no longer be displayed (thanks to Niels de Carpentier).
- Added the '-m486' option to the compiler call.
- If a channel name contains a colon (':') it is now replaced with a '|' in
  channels.conf.
- Not everybody appears to like the "page scrolling" mechanism introduced by
  Heino Goldenstein in version 0.61, so this is now configurable via the "Setup"
  menu.
- The new 'dvbrc2vdr' tool (thanks to Plamen Ganev!) can be used to convert
  'dvbrc' channel files into 'vdr' format.
- Channels can now be "grouped" (thanks to Plamen Ganev!). See MANUAL for details.
  There is currently no mechanism to define and maintain "Channel groups" via
  the menu, so you'll have to insert "Channel group" control lines into your
  'channels.conf' file manually (for example with a text editor).
- Started a new file named FORMATS with a description of the various file
  formats used by VDR.
- The "Primary DVB interface" can now be chosen via the "Setup" menu.
- Display of the "current/next" information when switching channels can now
  be disabled via the "Setup" menu.
- The "current/next" display now only shows those lines that actually contain
  information.
- When directly selecting a channel by entering the channel number, the digits
  entered so far together with the name of that channel are displayed on the
  OSD (suggested by Martin Hammerschmid).
