Voice tags at 0:04 should be closed when there are two voices in the same cue, or we'll get in trouble once we can display the voices.
Three cues at 15:13, 15:22, 15:32 were tagged as 10 minutes earlier, which caused them to overwrite the ones we needed starting at 05:13.
Some minor word differences.
