Hey guys im currently looking for the right tracker or right place were this release groups come from. I know they might be scene but would like to know if anybody knows ... I know IPT have some of their release but I would like to know were are they coming from.

You are right with your statement.
They are scene, which means they are not a group of any particular tracker.

With that said, every tracker which is specialized on scene releases is a good source for these groups.
TorrentLeech is one for example that has several releases from both.
