Geotiff should always work on QGIS. BTW, write support for ECW is still 
limited without a license.

Ubuntugis still holds ecw packages for GDAL 1.10 on raring, quantal, 
precise and lucid. So you can set up a virtual box inside your OS with 
one of those ubuntu versions, and install GDAL 1.10 with ECW support 
inside it to convert ecw files to Geotiff format. Data exchange between 
the virtual box and your host OS is possible with shared folders.

HTH,
