Gennady,

By default GDAL produces planar configuration "seperate" files - essentially
band sequential organization.  But the more common organization of TIFF files
is "single plane" or which is pixel interleaved.  Some applications only
support pixel interleaved.

If you add "-co INTERLEAVE=PIXEL" in the gdal_translate command, then the
more widely accepted form of the file will be produced.

I checked your files, and they seem to confirm the above problem.  The output
file looks fine in OpenEV.

The default to INTERLEAVE=BAND in the geotiff driver is quite dubious given
the compatability problems is has raised in the past.

Best regards,
