Unfortunately, as for now, it is not possible to access videos from Media Library.
See here the supported operations.

thanks for your answer! And it is mean that we don't have solution for get video files from Hub? – ShevninAnton Sep 24 '13 at 07:02

Unfortunately yes. That's the reason, for example, why some messaging apps (e.g. Whatsapp) don't allow to attach videos from library, although they allow to send videos recorded from the app. – anderZubi Sep 24 '13 at 07:17

Try SmoothStreamingMediaElement for audio and video hope it will help you
XAML
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="0.90*"/>
<RowDefinition Height="0.10*"/>
</Grid.RowDefinitions>
<SSME:SmoothStreamingMediaElement x:Name="video" Grid.Row="0" />
<!--TitlePanel contains the name of the application and page title-->
<StackPanel Orientation="Horizontal" Grid.Row="1">
<Button x:Name="PlayButton" Width="150" Click="PlayButton_Click" Loaded="PlayButton_Loaded"/>
<Button x:Name="StopButton" Content="Stop" Width="100" Click="StopButton_Click" />
<TextBlock x:Name="status"/>
<TextBlock x:Name="currentBitrate"/>
</StackPanel>
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"></Grid>
</Grid>
