I finally flashed this rom ! I did it like Rawqq said and everything works fine.
The point was to add this AriesVE.ops file (which wasn't included in rar archive) in Odin 4.43, then tick option "One Package" and add md5 image
If you don't add AriesVE.ops, you will get error "an unnamed file not found" which i earlier had
Quadrant score i have same as in 2.3.4 rom, but finally avi videos are being played correctly
(in 2.3.4 avi videos were played with very low framerate)
and as somebody asked, i can confirm that T9/swype is in polish and many other languages.
