• Only show the "duplicate" button when an audio/subtitle track is already selected. This should make it less likely that it's mistaken for the button to enable the track.
• Changed handbrake temp file cleanup to not use regular expressions. This should stop a mysterious intermittent issue caused by not being able to find System.Text.RegularExpressions.dll.
• Fixed issue that caused a delay in cleaning up old HandBrake temp files on exit.
• Updated HandBrake core.
• Removed presets with unsupported hardware encoders from the built-in presets list.
