RTMPDumper - Video seems corrupt?

[DyingToLive]

Hi,

I'm trying to download some video's from 3voor12 TV. I'm using this command:

rtmpdump -r rtmpe://fmss.vpro.nl/media/mp4:42384163.mp4 -o test.mp4

Had to resume a LOT! (Anyone know why?!) but when it's finished I do hear audio and see a still image. When I skip to later in the movie I see a still image of that particular frame, but no moving images. What am I doing wrong?

(I'm using 2.1b because 2.2c gave an error and this seemed to help)

EDIT! It's working in VLC BUT it's not very good. Stutters a lot, looks like it's only 10 fps or so. What can I do about that?
