Hotkeys. Definitely not done.

This isn't done yet. Although there are standard keys assigned now to 
the directx video window.

Skin specific? I'm already aposed to the whole skins idea. I think 
Hotkeys should be the same everywhere. It's one of my biggest 
annoyances of Windows, you never know which hotkey belongs to 
something. I always know on MacOSX.

Autogenerated menu's. This is being implemented right now. I think you 
will love this.

slider for the volume. Good point. where is it? well i know at least 
the prefs have sliders now for certain values, i think this control 
definitely needs to be added before release.

I'm not sure about this status. Actually i'm not even sure this can be

If you fix the above, i think you automatically fix this. problem.

It does this? i thought it only quit when you hit the close on the 
video output. (Which also is bad btw).

VLC media player to be exact.  and no i didn't get the point completely

At the moment it's preferable over the old way in which we didn't do 
this. I agree though that one of the things i liked about the old 
method is that you could watch a two part movie, without a flicker 
between them.

Mmm, please do so if you can reproduce this, but it might be a windows 
only problem of course.

That's stuff for walken.

I'm for Messages, it's the name used in all interfaces.

That's great. one more bug down the drain.

I'm not sure if we should.

I agree, we need to have an aspect ratio and 'crop blackbars' menu. 
It's really annoying seeing 16:9 video encoded in 4:3 on a 16:9 screen. 
And people do that a lot. However i don't think this is gonna make it 
to 0.6.0 It's something for a next release.

Yeah, but we want a way that works on every platform of course ;)
There was someone on the list working on this, but i haven't seen much 
of him for some time.

Good thinking.  i agree that volume is a better choice then screensize.
I've been thinking of implementing this for osx for some time.

It's inherent to the VLC structure which uses packets. fenrir just 
mailed that he would start on a new input code after 0.6.0 to be able 
to fix all this. John Zorko (list) is also working on this. This one is 
realy big in the amount of effort it will require to fix.

So in short:
What needs to be done now:
- shortcuts for menu entries.
- slider for the volume
- check float on top
- contextual menu close behaviour on windows
- directx window close behaviour
- drag and drop playlist behaviour
- menu entry "Logs" -> "Messages"
- fix the problem fixed by gildas test release to you

What we need to fix
- menu entries for window zoom
- file association
- libmpeg2 crashes
- aspect ratio/crop menu
- screenshot plugin
- mousewheel behaviour
- fix packet/frames issue

Thanks again for bringing all this to our attention.
