Why do the PRIDE FC DVDs take so long to release?

Due to unforeseen and unexplainable circumstances, the PRIDE FC DVDs stalled at PRIDE 18. Since then we've been working diligently to catch up in the DVD sequence (and not fall so far behind again). The goal is to simultaneously release the older titles along with the more recent titles, in essence working backwards and forwards at the same time. In addition, we are working to provide the best possible product, so this sometimes requires extra time.

 

Why does PRIDE FC cut out fighter introductions on the pay per view and DVD?

When fighters come out to unlicensed music, these segments must unfortunately be cut out.
