Yes, this is known problem for me. The thing is that the layout of maps on 
Seznam.cz is different then the a layout of the rest of supported maps. Both 
the position of the tiles and their scale factor is different. The problem is 
described in detail in the source file gmapcatcher/mapServers/seznam.py. 

A possible solution is to use internally GPS coordinates in GMC and recompute 
it to tiles for each map server. It would require that each file 
gmapcatcher/mapServers/  contain a function which computes from a GPS 
coordinate x, y coordinates of the tile, which contains the place and also some 
offset from the tile corner. As far as I know, GMC does not have such 
functionality yet. 

I think that the owners of this project must decide whether they agree with 
such a big change.

Nevertheless I hope that GMC is a valuable tool who want to download for their 
personal use maps from seznam.cz and view them offline.
