Well as some of you may know Wizard of Oz is being rereleased on video this year for like the 600th time!! :P Unlike the last couple releases which included a 5.1 track and the original mono track this release only features the 5.1 drops the mono track. Is this a loss?? Were changes made for this film's 5.1 track?????

Not really. The 5.1 mix is made of 3 parts:

1. Restored mono track

2. Isolated orchestra angles

3. Isolated music and effects track

Out of all of these, there is but one change found only on the mono track and that is the removal of Judy Garland's stutter around when she says "Oh, Toto!" in Kansas. And really? They are removing the mono track for the 3d rerelease this year? What's your source?
