Your copy of GDAL has to be built with support for those formats. Once it
is, r.in.gdal should be able to read it.

check with:
 gdalinfo --formats

if ECW is not there you will need to rebuild GDAL with support for those.

I am pretty sure that ECW support is not built by default.
 see http://www.gdal.org/frmt_ecw.html

Now that ERmapper has been bought by Leica (apparently erdas has too),
obtaining the SDK has changed as they have a much different view of open
source:
"Product enhancements, including:
  * no more restrictions on the distribution of 'Server Software' under
the GPL-style Public Use License Agreement"

.... but what has that been replaced by? Moved to BSD-like or proprietary?
The binary SDK is only available for Windows, so you may be forced to use
GDAL for Windows to export to GeoTiff.   ? Hopefully the new license is
usable for Linux, I don't know. They still offer the source, which is
encouraging.



good luck,
Hamish
