Can't encode Quicktime .mov files

[Mr.Ash]

How can i convert QT movies with:

- Motion JPEG A Video / ulaw 2:1 Audio

or

- Component YCbCr 8bit 4:2:2 Video / Uncompressed PCM 16bit stereo Audio

to

MPEG4 using the 'DivX mencoder' or 'Xvid mencoder' engine. That's important cause of the denoise, deblock and dering options. Also i can't make any corping or preview (mplayer starts and quits immediatly). The encoding also starts and quits immediatly giving me this text:

mencoder can convert Quicktime mjpeg A+mulaw. However, it can't convert Quicktime Component Video.
