Description: fix ASX playlist parser
Basically our asx parser is broken. It doesn't handle relative links. It should also URL encode the hrefs (spaces in the url need to be converted to %20 etc). protocol rollover, authors, title's etc etc aren't handled. See <a href="http://www.meetnewplayers.com/bend/Windows%20Media%20-%20Fun%20with%20asx%20files2.htm">this</a> for asx examples. It is still located in the old demux/m3u.c module instead of modules/demux/playlist/

Description: LPCM
The LPCM decoder outputs really small samples which aren't accepted properly by the macosx coreaudio resampler, causing VLC to not output any sound with many DVD's. A test sample that shows this effect on the mac is the Madonna clip.<br />
This is now fixed, but there is a problem with buffers in the resampler that now sometimes overflows (or rather get changed after they are released). A good method for reproduction seems to be running Finding Nemo for a minute or 8.

Description: Vout redesign
- vout needs distinct splitting into vout_core, vout_window, pic_filter, vout_filter<br />
- needs 'assistance' vout windows (clone filters, goom) etc.<br />
- 4:3, 16:9, freeform Aspect Ratio<br />
- cropping and padding (do at OS level, but provide a core call to set it up and configure).<br />
- OSD at window resolution instead of video res (secondary vout channel)<br />
- a OSD needs to be bound to a vout stream (no subs on goom vout)<br />
- Use OS native calls where appropriate, with 'C' fallbacks. (OpenGL, Quartz, DirectX already has many of the funtionalities we seek and sometimes they are a lot faster too).<br />
- Allow a vout to reuse a window by resizing it (instead of closing and opening).
- better hotkeys integration

Description: skins2
Port VLC skins to Objective C++ and OSX. Also requires the intf to be a dialog provider. There is already some code in the VLC sourcetree.<br />

- In a first step, the need for a dialog provider can be easily omitted.<br />
- In theory, only a small amount of classes (6 or so) must be written for OS X, implementing predefined interfaces.<br />
- The code of <a href="http://www.fltk.org">FLTK</a> could be really helpful to identify the correct functions and see how to use them.

- Inform the user, without disturbing him. (Buffering stream). This might require a displaytime or something. Because how do we know how long this information should be displayed? Also think of buffering 0-100%<br />
- present a user/passwd dialog when we get an authentication failure on a stream.<br />
