Executing the command "vlc -I qt4" should start VLC with its default interface. Then you can access the settings and disable skins. Although I believe having deleted ~/.vlc should have already disabled the skins mode and reactivated the normal interface.
enlarging on question 1, these IDs you saw in that skin were chosen by the skin author. You see in the beginning the list of bitmaps and so forth were image files are given certain ids. As erwan said, this is entirely up to the skin author, how he organizes that. To question two, I never checked it,...
This feature is not available for skins at the moment. The skin interface is and probably will be limited in many ways, compared to the native interface. This is just because they are two separate interfaces with different feature sets. And most of the development time goes into the main interface n...
You also have to click "OK" in the slider editing window. Only after you do that the generated slider is applied. Just check in your bitmap section if an image has been added, if so then the background generator ran through successfully. Otherwise it anyway should have given you an error m...
Not all advanced controls can be included in skins at the moment. But the controls for recording and frame-by-frame playback are available. If they are not in the skin you use, then the designer chose not to include it.
If your iPad is jailbroken, you can still get VLC on it. You can download the VLC app here: http://www.videolan.org/vlc/download-ios.html Extract the zip file and drag VLC.app into iTunes. To install it then on your iPad sync your apps with iTunes. Alternatively, get the .ipa file that iTunes create...
I've stopped work on the skin designer, I don't have the time to maintain it anymore. And so far nobody else was interested in helping the development.
Directly move the slider (change the x,y coordinates of the slider object). Also you can move the slider points (which define the path along which you can move the fader/knob/whatever its called. The coordinates of the points are relative to the upper-left corner of the actual slider object.
Most of the skins use their own fonts. Usually the fonts that are included in the skins do not support non-latin characters. You would have to extract the vlt file (they are actually justs zip or tar.gz archives) replace the included font with one you like and pack it up again.
These previews are generated automatically by Windows (See http://en.wikipedia.org/wiki/Windows_thumbnail_cache). Afaik there is no tool existing with which you could modify them. And if you would change them, there would be no guaranty that the changes are kept, as Windows will update these thumbna...
That old interface has been discontinued because of various reasons (iirc it was to buggy and not comfortable to develop). The skins engine is too limited to reproduce the look and feel of that old interface. I think you have to live with the current interface or use some other skin. But the old int...
This error message indicates that some SubBitmap used in the skin is too high. You'd have to open the XML file with a text editor and find that SubBitmap manually and correct its height.
There was a Google Summer of Code project in 2010 that dealt with porting VLC to Symbian, but I'm not sure about it's current status. According to the VideoLAN wiki VLC does not yet support Symbian.
