Any sequence that has an .flv file at the start looks fine in the editor, but when exporting the first half second of video plays twice, resulting in audio being half second ahead for the rest of the video.
This appears to only happen with .flv files, testing with .mp4 doesn't have the same issue. It's also "resolved" by having a small (sub second) gap between the start of the timeline and the flv video. It happens regardless of the format exported into.
I think I have a workaround, but a fix or setting I may have wrong so I don't have to manually add these little gaps would be helpful.
Thanks!

After more testing it seems like the workaround only sometimes works, and only reduces rather than eliminates the section of the video that is replayed.
