The key point when posting a bug is to give me as much information as possible so that I can re-create the bug. Broadly speaking - if I can recreate the bug, then I can fix it.
Let me know how and where you are seeing the problem.
Let's say there is a problem with VLC Remote. Key information would be:
Device : iPhone 4 running iOS 4.2 Computer : Windows Vista Home Premium 64bit VLC : version 1.1.6
The key point here is to help me follow your steps, and to let me know what you expected to happen
expected : Movie would play on computer
actual : VLC started playing the previous track that I had opened and displayed an error message on the computer
detail: The error message said 'We don't think you'll like that movie, so we are playing some music'
Screenshots are often very helpful.
In this case - perhaps a screenshot of the error message on the computer.
(to take a screenshot on an iPhone/iPod/iPad, just click the home and power keys at the same time. You'll hear a click and the screenshot will be saved in your photos)
