Errors when importing video to iPod Touch

Does anybody noticed errors (video not recognized) when importing videos to an iPod Touch ? Mine is 3rd Gen.
I’m using Gtkpod 2.1.1. OpenSuse 12.1, 64bit, LXDE desktop.

MP3 files import ok, only videos are the problem. Check to make sure all libraries and codecs are installed.
Videos converted using Handbrake, using the iPhone/iPod Touch preset.
I’m sure it’s a problem that ocurred since the latest updates of Gtkpod.

Thank you
