QuickTime to MP4 for Nokia N95

I have a new Nokia N95 cellphone, which plays "mp4" files.... But not all mp4's.

Most of my iTunes "mp4s" will not play on the N95, but if I use QT player to export the files to mp4-improved, 512 kbps, 320x240 QVGA, AAC 128kpbs -- then this works.

However, I'd like a one-step converter that makes videos which will play on BOTH my N95 and my 5G iPod ?

Does anyone know of a converter that will take my QT movies and convert them to play on the N95 --AS WELL AS-- my iPod ?

Thanks
