Initial Comment:
the another ticket with this problem was closed (https://alioth.debian.org/tracker/?func=detail&atid=413085&aid=312321&group_id=100070) so i'll open this new one.

here my information:

same problem here. it's a axel bug with youtube server, because when i'll try to download a video form youtube, i'll get the same "HTTP/1.1 400 Bad Request" error:

HTTP/1.1 400 Bad Request
--------------------------

when i'll use tcpdump and looks what happening here, i can see that the youtube server answer with a "302 FOUND" and with a NEW download link:

--------------------------
HTTP/1.1 302 Found

--------------------------

when i'll try now this new download link with axel, it's working perfect. so axel doesn't considered the 302 found with the new download link.

i'm using debian 6 (64 bit) with axel (2.4-1). (installed via apt-get install axel)

hope anyone can fix this bug asap.
