convert/record : audio is fine, but video not recorded

Hello,
I want to digitize videos from my camcorder.
To do this, I bought an AV to USB converter.
With VLC, when I capture in playback mode, everything is fine
I select my capture device, and I can see the live stream (directshow) video + audio on VLC.
But if I want to use "convert/record", although I select the same capture device, and mention a file to record, even if I change the recording formats (video for divx, video for MPEG4 720p...), I get a file that contains only the audio, and not the video.
And during capture, the video isn't displayed in VLC either.
Could you help me?
Thank you for your help.
Let me know if my description isn't clear enough.

Please open Tools -> Messages (set Verbosity to 2) before you start the recording, and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

Hello,
Sorry for the delay in my reply.
Here is the copy/paste of the messages :

(it was too long to paste here)
I first did a "read" sesssion before doing a "record" session.
Thank you very much for your help !!

etc etc again and again, and then:

Let's hope a dev will check that.

Hello,
Thanks for your reply.
As I was not able to find a solution with VLC, I used another tool which worked immediatly.
Name of the tool : CaptureFlux
