I have some of those but on mp3, on the videos, I have the same you do. I don't have any problem sharing what I have, but I know of some people who have MASSIVE bootleg collection of X concerts on audio and video who only trade them for even more impossible bootleg concerts. Most of the bootlegs were on the WinMX, but since its down, I have no idea where to get them.
On mp3 I have
1993.12.31 X Japan Returns, Nihon chokugeki countdown (except for COUNT DOWN~X that is from the LIVE x3)
1994.12.30 Tokyo Dome, ~Blue Night~
1994.12.31 Tokyo Dome, ~White Night~
1995.11.13 Dahlia Tour Studio Rehersal
