I don't think it's TVB that is doing the compression. It's the distributor which is Tai Seng. They decided to not go with TVB's direct transfer and started using their own masters and just compressing it. I guess it saves them money. DVD's released straight from TVB are higher quality, especially the new ones that are shot in High Def. I think it's Tai Seng unless they are no longer the distributor for the United States.
