[FFmpeg-user] Encoding from video input results in damaged video

I'm encoding audio and video from an old camcorder via USB capture device.
This is my command line string:

ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 -c:v h261
-f alsa -i hw:4,0 -c:a mp3 frankreich.mp4

Unfortunately the resulting video is damaged, picktures show a strong
flicker, it sometimes jumps back to quite an old frame (a few ones only)
and there are strong interlace lines.

Any ideas how to correct this?

I also think I should the PAL-format somewhere.
