Look around for 'WEB-DL.DD5.1.h.264', groups such as TjHD, CtrlHD, PiLAF, McRipz etc do them. I don't know about trackers have them, I've seen them on tehPARADOX (DDL Site), Usenet and a few on IPT, Demonoid.
Havent been on any HD trackers in ages, but i would assume there would be a few on Bit-HDTV?
Once 15 days pass since your registration, you'll have access to the invite areas. You may then post a request. HDBits.org will be very tough to get into, but Bit-HDTV will be easier.
Requesting on other sections may get you warned or banned, so don't. In the meantime, feel free to be active and helpful here so that you're considered for an invite
