Hal Leonard DVDs are standard DVDs. They can only be played in DVD players. They will not work with the Fretlight software to light up a Fretlight guitar.
The Fretlight Ready version of the Hal Leonard videos will only play in the Fretlight Video Player software. The Fretlight Ready version of the Hal Leonard video does not include the Hal Leonard DVD's "jam track" that has the guitar track muted.
