I'm using VLC 2.0.2 to stream videos from YouTube and I'm hitting the "Record" button at times so I can store the more interesting parts of the stream on my PC. I was using this just yesterday and it was saving the clips as .mp4 files, which was great. I just started using it again today, and it's now saving them as .avi. This would be fine, but for some reason the playback is messed up (the timing is all off) and there's no audio. I'm only doing this for the audio, so that's important.
How can I tell VLC I want to record the current playback as .mp4?
