tsunami bullshit

Eclipse's raw for Full Metal Alchemist: Brotherhood has the bullshit 90cm tsunami warning map plastered all over it.

But I was browsing Tokyo Toshokan and found a .mp4 release from another group using Eclipse's subs that doesn't have the map, but has that group's credit in the upper left corner of the screen for the entire episode.

I'm wondering if I can't use aegisub to somehow remove that credit.  Or if I can find a 720p h264/Vorbis .mkv raw without the map, could I just pull Eclipse's subs out of their release (they're just softsubs) and stick them on that.

I wish I understood better how this shit worked.
