THey AREN'T delaying the DVD, they are delaying the VHS, due to the Spider-man trailer on it.
The DVD DOESN'T have the teaser on it. SO it won't be delayed.
------------------
According to dvdfile, the VHS tape will be delayed 3 days in order to remove the trailer of the upcoming 'Spiderman'. The WTC twin towers were featured in the trailer. Because of the sensitivity to the recent tragedy, the studio is going to remove the trailer. However, the DVD will be released as scheduled because this trailer was never included in the DVD version.
