Download Service Utility - Fails with hyphen's

I've just noticed the Download Service Utility struggles to match files with hyphen's.

In my GameCube collection I have

18 Wheeler American Pro Trucker (USA)

On the EmuMovies FTP I can see there is a

18 Wheeler - American Pro Trucker (USA).mp4

but Download Service Utility doesn't manage to match these two files.

Same goes for

Army Men Air Combat - The Elite Missions (USA)
Army Men RTS (USA)
Beach Spikers (USA)
Beyblade Super Tournament Battle (USA)
Bust a Move 3000 (USA)
Cabela's Big Game Hunter 2005 Adventures (USA)
Capcom vs. SNK 2 - Mark of the Millennium (USA)

Army Men - Air Combat - The Elite Missions (USA).mp4
Army Men - RTS (USA).mp4
Beach Spikers - Virtua Beach Volleyball (USA).mp4
Beyblade VForce - Super Tournament Battle (USA).mp4
Bust-A-Move 3000 (USA).mp4
Cabela's Big Game Hunter - 2005 Adventures (USA).mp4
Capcom vs. SNK 2 EO - Millionaire Fighting 2001 (USA).mp4

but Download Service Utility misses these
