It's also F Major.

Close. The notes of D minor and F major are common, but the key of the song will determine which scale you are actually playing.
And no, Guitar Hero will not help. Even on expert. Really.
If your root note was F it would be an F Major but since it is a D then it is a D Minor. You can always find a major's parallel minor scale by using the 6th note in the scale as the root.

It can't be both.

Saying "Or F Major" would have been correct because we don't know the root so it could either be D (natural) minor starting on the root (admitedly more likely) or F major starting on the 6th.
