Yep, didn't expand with :lzo
Maybe wrong codec in arc.ini? lzo2.dll is in place
Edit: You have to use
for Origins

Code:
DataPC.forge (ACO)
xtool v0.7 oodle: 273.088.512 Bytes => 574.853.120 Bytes
AFR: 273.088.512 Bytes => 574.849.024 Bytes
From this example xtool and AFR have pretty much the same compression speed (AFR is a little bit faster, but just a few secs)
