I don't understand why precious Mac resources are going to Lunettes at a time when Mac Dev resources are stretched so thinly. Wouldn't a minimalist approach of porting VLC properly with as few platform-specific customizations as possible make more sense in light of the current resource situation? I ask with utmost respect for the Developers who are dedicating their time to the project.
See it as an investment. The idea is by creating an application that is designed with MacOS X in mind, it will become easier to support and maintain. Then, because of that, anyone with more core experience of MacOS X development will find it easier to contribute. It should also help provide a better user experience to the Mac community. If you have ever used Adium, then think of the relationship as being the same between Adium and Pidgin.
Developers are free to decide how they want to spend their energy. In the same vein, users a free to decide whether they will accept an application developed by volunteers.
Providing logs, messages, configuration info (VLC, OS, Hardware) and a clear explanation of the issue always helps the problem solvers help you, even if they don't end up solving the issue. Just think what you would need if you were solving someone else's problem. Additional: Always looking for eager and capable MacOS X developers to join the VLC team - for more information
