I don`t know what format the original posky files are in but loading them into DXTBmp will tell you.
DXTBmp will also let you save a copy of the texture in a format fsrepaint can handle. Again I don`t know what this program can take but it should be able to read 32 bit. I thought fsrepaint worked directly on the model in FS and so should really be able to handle all the FS formats. If it is working but you don`t like the results load the finished texture into DXTBmp and then save it out in 32 bit without mipmaps.
This should reduce the blurries.
