I mostly take texts from libraries with books in fb2 format like aldebaran.ru and then use the program fb2lrf to convert it to LRF format. I took this program from
http://www.msh-tools.com/ebook/fb2lrf.html site. Then I would load this LRF file to Calibre.
Sony's ebook Library software is able to read those LRF files fine.
Finally I think I resolved this problem. I just skip this stage with FB2LRF convertion and load Calibre directly with FB2 file and I was able to view those file fine after that.
