Please update support for canalplus.fr

This is no "add-support" request, since you already do have support for canalplus.fr.

Unfortunately something was changed through the last months:

user@my-lubuntubox:~/tmp# echo && cat debug.log

This happens with latest build.

Oh, besides, I checked first, and found this is NOT a duplicate: the other user's error message was
ERROR: unable to download video data: HTTP Error 403: Forbidden

while mine is about f4m manifest file, thus a little more specific. (Unless merely the error message has been made more specific meanwhile ;))

This video is geo restricted (works perfectly via french proxy). Can you watch it in browser?

[andreas--e]

Confirmed, yes, does work in French proxy, albeit paiiiinfully slow (as for these one-off cases, it literally doesn't "pay off" registering at a proxy which requires a fee to use, so I took a free one instead).

But as already requested by a user in Issue #4516, this non-descriptive error message ought to be replaced by one that the user can understand, one that is not only remotely hinting at the problem. (since an "Error 403" may get triggered by a plethora of different issues)

In the next version it will give a proper error message, thanks for the report.

Thank you very much!
