Short answer - if playing by the rules as written, when you play a card you declare your intent first, allowing others to do the same, and then reveal them immediately. Then they are resolved in initiative order.If Direct Hit ends up going first, it takes effect, blows up the ships, and the repairs won't help it (though they will still repair any other ships).
If Emergency Repairs goes first, it will basically "block" the direct hit.
See the thread above for more in-depth discussion, though :)
