I own a Canopus DV REX M1 and it is THE best investment I have ever made. It works excellent with premier. I also use MSP 5.2. It is well worth spending the money. Als o be sure to buy a videoraid. It is expensive, but the support is incredible!!! There may be cheaper alternitives, but you may not be as happy with those as you will with this. Go to www.canopuscorp.com and check out the REX Users forum. It is Great!!!(posted 9125 days ago)
