I fixed a couple of errors I was experiencing with current git builds.
I attached the patches, they might be useful..

Explanation:
1) default_sortorder.patch:
This sets the default sortorder in channel-grid (navigate: Configuration/Channels) to "ascending sorted by user assigned number".
This effects almost all channellists within the app, for example this also changes the channellists presented by the dropdown selectors (i.e. elecronic-program guide channel-selector or vlc-windows channel selector).

2) mime_type.patch:
This changes the M3U playlist return mime-type from "application/x-mpegURL" to "audio/x-mpegurl". According to (http://www.w3schools.com/media/media_mimeref.asp) this is more correct (there's no application/... variant). After changing, my browsers automatically suggest the ".m3u" extension for downloaded-file when opening the URL. for example this enables .m3u downloading and auto-opening also by Internet Explorer. (did not work before, no recognized mime-type).

3) tune_chconf_grid.patch:
This fixes the "Play" link in channels-grid, that was pointing to the playlist url instead of the stream. It also adds another column with a direct M3U download link.

4) tune_epg_grid.patch:
This adds 2 new link-colums to the EPG-grid, one for M3U download and one for direct play within embedded player. to avoid opening the popup when clicking the links, the click-handler design was slightly adjusted.

5) tune_vlc_popup.patch:
This contains lots of fixes and improvements for the vlc-player windows, they are

• Enable resize for player-window (inner vlc-plugin autoscales to 100%, allows movie-resize during playback)
• Fixes channel-switching (didn't work before here, it played always the same channel)
• Enables multiple vlc-playback-windows for parallel playback of more than 1 stream
• Adds a message to fullscreen-button click, that fullscreen mode is broken in VLC 1.1.x if VLC plugin 1.1.x is detected
  (see http://forum.videolan.org/viewtopic.php?f=4&t=82721&p=274383, last known version to work: 1.0.5 <- that one has no DXVA for example :( )
• Now shows M3U and DirectStream URL if plugin is missing in BOTH cases (there were 2 in code)

Please review these patches carefully, I'm new to tvheadend :)
I have also some more improvements in mind, for example the VLC plugin supports setting deinterlace-settings...

with kind regards,
