\section{Introducing the Main Menu}
\screenshot{main_menu/images/ss-main-menu}{The main menu}{}
The \setting{Main Menu} is the screen from which the rest of the Rockbox functions can be 
accessed. It is used for a variety of functions, which are detailed below. 
All options in Rockbox can be controlled via the \setting{Main Menu}.

To enter the \setting{Main Menu}, 
	\opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{press the \ButtonMode\ button.}
  \opt{RECORDER_PAD}{press the \ButtonFOne\ button.}
  \opt{PLAYER_PAD,IPOD_4G_PAD,ONDIO_PAD}{press the \ButtonMenu\ button.}
  \opt{IAUDIO_X5_PAD}{press the \ButtonRec\ button.}

All settings are stored on the unit. However, Rockbox does not spin up 
the disk solely for the purpose of saving settings.  Instead, Rockbox will
save settings when it spins up the disk the next time, for example when 
refilling the MP3 buffer or navigating through the file browser. Changes to 
settings may therefore not be saved unless the \dap\ is shut down safely 
(see page \pageref{ref:Safeshutdown}).

\section {Recent Bookmarks}
\screenshot{main_menu/images/ss-list-bookmarks}%
  {The list bookmarks screen}{}
If the \setting{Save a list of recently created bookmarks} option is enabled 
then you can view a list of several recent bookmarks here and select one to 
jump straight to that track. See page \pageref{ref:Bookmarkconfigactual} 
for more details on configuring bookmarking in Rockbox.
\note{This option is off by default.}

\section{Sound Settings}
The \setting{Sound Settings} menu offers a selection of sound properties you may 
change to customize your listening experience.  The details of this menu are 
covered in detail starting on page \pageref{ref:configure_rockbox_sound}. 

\section{General Settings}
The \setting{General Settings} menu allows you to customize the way Rockbox looks 
and the way it plays music.  The details of this menu are covered in detail 
starting on page \pageref{ref:configure_rockbox_general}.

\section{Manage Settings}
The \setting{Manage Settings} option allows the saving and re-loading of user 
configuration settings, browse the hard drive for alternate firmwares, and finally
to reset your \dap\ back to initial configuration. The details of this menu are 
covered in detail starting on page \pageref{ref:ManageSetting}.

\section{Browse Themes}
This option will display all the currently installed themes on the \dap, 
press \ButtonRight\ to load the chosen theme and apply it.

A theme is basically a configuration file, stored in a specific directory, 
that typically changes the WPS 
\opt{h1xx,h300,x5}{and remote WPS}, font used and on some platforms
additional information such as background image and text colours.

There are a number of themes that ship with Rockbox. If none of
these suit your needs, many more can be downloaded from 
\opt{RECORDER_PAD}{\wikilink{WpsArchos}}%
\opt{h1xx}{\wikilink{WpsIriverH100}}%
\opt{h300,ipodcolor}{\wikilink{WpsIriverH300}}%
\opt{ipodvideo}{\wikilink{WpsIpod5g}}%
\opt{ipodnano}{\wikilink{WpsIpodNano}}%
\opt{ipodmini}{\wikilink{WpsIpodMini}}%
\opt{x5}{\wikilink{WpsIaudioX5}}%
.
Some of the downloads from this site will actually be standalone WPS files, 
others will be full-blown themes. 

\note{Themes do not have to be purely visual.  It is quite possible to create
a theme that switches between audio configurations for use in the car, with
headphones and when connected to an external amplifier.  See the section on 
``Making Your Own Settings File'' on page \pageref{ref:CreateYourOwnWPS} 
for more details.

    \item[Quality:]
      Choose the quality here (0 to 7). Default is 5, best quality is 7, 
      smallest file size is 0. This setting effects how much your sound 
      sample will be compressed. Higher quality settings result in larger 
      MP3 files.
      
      The quality setting is just a way of selecting an average bit rate, 
      or number of  bits per second, for a recording.  When  this setting 
      is lowered, recordings are compressed more (meaning worse sound quality), 
      and the average bitrate changes as follows.

  \item[Frequency:]
    Choose the recording frequency (sample rate) -- 48kHz, 44.1kHz, 32kHz and
    24kHz, 22.05kHz, 16kHz are available. Higher sample rates use up more disk
    space, but give better sound quality.
    This setting determines which frequency range can accurately be reproduced
    during playback, Lower frequencies produce smaller files.
    \opt{MASCODEC}{
     The frequency setting also determines which version of the MPEG standard 
     the sound is recorded using:\\
     MPEG v1 for 48, 44.1 and 32\\
     MPEG v2 for 24, 22.05 and 16\\

  \item[Channels:]
    This allows you to select mono or stereo recording. Please note that 
    for mono recording, only the left channel is recorded.  Mono recordings
    are usually somewhat smaller than stereo.
    
  \item[Independent Frames:]
    The independent frames option tells the \dap\ to encode with the bit
    reservoir disabled, so the frames are independent of each other. This
    makes a file easier to edit.
    
  \item[Time Split:]
    This option is useful when timing recordings. If set to active it stops 
    a recording at a given interval and then starts recording again with a 
    new file, which is useful for long term recordings.
    \newline
    The splits are seamless (frame accurate), no audio is lost at the split 
    point. The break between recordings is only the time required to stop
    and restart the recording, on the order of 2 -- 4 seconds.
    \newline
    Options (hours:minutes between splits): off, 24:00, 18:00, 12:00, 10:00, 
    8:00, 6:00, 4:00, 2:00, 1:20 (80 minute CD), 1:14 (74 minute  CD), 1:00, 
    00:30, 00:15, 00:10, 00:05.
    
  \item[Prerecord Time:]
    This setting buffers a small amount of audio so that when the record button 
    is pressed, the recording will begin from that number of seconds earlier.
    This is useful for ensuring that a recording begins before a cue that is
    being waited for.\\
    Options: Off, 1 -- 30 seconds
    
  \item[Directory:]
    Allows changing the location where the recorded files are saved. The
    default location is \fname{/recordings}.

    showing.\\

\section{\label{ref:playlistoptions}Playlist Options}
  This menu allows you to work with playlists. Playlists can either be created
automatically by playing a file in a directory directly, which will cause all 
of the files in that directory to be placed in the playlist, or they can be
created by hand using the \setting{File Menu} (see page \pageref{ref:Filemenu}) 
or using the \setting{Playlist Options} menu.  Both  automatic and manually 
created playlists can be edited using this menu.

\begin{description}
\item[Create Playlist:]
  Rockbox will create a playlist with all tracks in the current directory 
and all subdirectories. The playlist will be created one folder level ``up'' 
from where you currently are.
  
\item[View Current Playlist:]
  Displays the contents of the playlist currently stored in memory.
  
\item[Save Current Playlist:]
  Saves the current dynamic playlist, excluding queued tracks, to the 
specified file. If no path is provided then playlist is saved to current 
directory (see page \pageref{ref:Playlistsubmenu}).
  
\item[Recursively Insert Directories: ]
  If set to \setting{On}, then when a directory is inserted or queued into a 
  dynamic playlist, all subdirectories will also be inserted. If set to \setting{Ask},
  Rockbox will prompt the user about whether to include subdirectories.
  Options: \setting{Off}, \setting{Ask}, \setting{On}

\item[Warn When Erasing Dynamic Playlist: ]
  If set to \setting{Yes}, Rockbox will provide a warning if the user attempts to
  take an action that will cause Rockbox to erase the current dynamic playlist.
  Options: \setting{Yes}, \setting{No}
\end{description}

\section{Browse Plugins}
  With this option you can load and run various plugins that have been
written for Rockbox. There are a wide variety of these supplied with
Rockbox, including several games, some impressive demos and a number of
utilities. A detailed description of the different plugins begins 
on page \pageref{ref:plugins}.

\section{\label{ref:Info}Info}

remaining, disk total space and disk free space.
\opt{player}{Use the MINUS and PLUS keys to step through several 
pages of information.}

\begin{description}
\item[Rockbox Info:]
  Displays some basic system information.  This is, from top to bottom, 
the amount of memory Rockbox has available for storing music (the buffer),
battery status, hard disk size and the amount of free space on the disk.
  
\item[Version:]
  Software version and credits display.
  
\item[Debug (Keep Out!):]
  This submenu is intended to be used \emph{only} by Rockbox developers.
  It shows hardware, disk, battery status and other technical information.  
  \warn{It is not recommended that users access this menu unless instructed to
