problem with converted QT to MXF with File converter 1.2

Hello,

We a nanoflash that we use as transfer device. We want to use it with both FCP and Avid MC. We recorded some footage as 140mbit I-frame QT then converted with your utility. The converted MXF cause an error of unsupported resolution when we try to import to Media Composer 4.03

The QT worked fine in FCP and the converted MXF played in VLC (sort of,aspect ration seemed to be detected wrong). Seems like an error in the metadata of the MXF file. We want to keep options open since some students work at home with FCP an others with Avid at our facility, hence recording in QT, buy hope to get the MXF convertion working too.

Any clues??

THanks

Marcus
