Jiri,

I am a bit surprised that you are encountering these problems.
The mapresample.c code should be kicking in for rotated input
rasters, and it should not be overlaying existing information with
"blankness" from outside the original files.  I am assuming that your
source files don't have any blank rectangles in them - is that right?

If you can submit a bug report with sufficient information for me to 
reproduce the problem (ie. pointers to a map file and data files I
can use) then I can try to look into this.   Make sure the bug report
gets assigned to me. 

Best regards,
