But anyway: I was happily surprised to see there are still a few seeds on an old torrent for one of the OAR broadcasts. It's a 25.0GB 1080i H.264.

Were there every any other transport streams shared?

Is the broadcast of Titanic you have 1080i 25fps (bitrate: 17880 kbps)? If so, it's the same one I have.

I ended up muxing a decent custom BD for myself, slowing it down to 23.976 and adding the DTS from a (film-speed) 720p HDTVrip. Thankfully, no additional syncing was required.
