M-Team and CHDBits have almost the same new mainstream Blurays when Looking at the internal Uploads, however you can find a lot of different Uploads on both Trackers from the members, while there are Uploaders who spread them across various chinese trackers all the time. usually scene content, and sometimes from other sites or even original Uploads, but probably not so much of them.

HD Trackers usually don't support DVDs, as they are per Definition not HD material. But there's one Tracker called Blutopia, which also allows DVDs, Blutopia has one of the easiest upload forms, making it an attractive Tracker for some well known P2P uploaders who usually upload on other well known teackers like HDBits or Cinematik.

for DVDs, Cinematik is also very interesting, but they only have old/Arthouse/non-USA content.

For a good selection of available Content, a lot of Trackers will help. If you don't want to many of them, or don't want to buy an HDBits invite for a few hundred bucks, I would recommend HD-Torrents and Bluropia, it's quite easy to get access to them.
