Ok it's all now online at fanedit.info, including the 2 new Building Empire DVDs as explained here : http://originaltrilogy.com/forum/topic.cfm/BUILDING-EMPIRE-PAL-NTSC-DVD-NEW-EDITION-NOW-ONLINE/post/452102/#TopicPost452102
At moment, the rar/dlc file for RTJ SL PAL is wrong (it loads the DL PAL links)
But for now it can be found inside BE's SL PAL rar file (which has both SL PAL dlcs)
Links are now fixed.
Just to be sure, the download size of each dvd is:
RTJ DL PAL: 4.37 gb
RTJ SL PAL: 4.19 gb
RTJ SL NTSC: 4.20 gb
