Suppose one tries to download certain videos from Google Video (most, probably), such as http://video.google.com/videoplay?docid=-5629273206953884671

Clive fails to:

gwern@craft:18513~>=clive 'http://video.google.com/videoplay?docid=-5629273206953884671' [ 3:37PM]
clive/0.4.3 (linux2; python/2.5.2; urlgrabber/3.1.0)
[log:on] [play:off] [encode:off] [throttle:off] [existstatus: 9KB (1 of 1) [http://video.google.com/videoplay?docid=-5629273...]
error: OSError: [Errno 2] No such file or directory: '/home/gwern/-5629273206953884671&hl=en&fs=true' [http://video.google.com/videoplay?docid=-5629273206953884671]
status: checking file length... queue: 0 (total: 0.000MB), failed: 1, skipped: 0.
error: nothing to extract.

But nevertheless, it is possible for software to download it. Consider the web download service KeepVid. It has no trouble with this link: http://keepvid.com/?url=http%3A%2F%2Fvideo.google.com%2Fvideoplay%3Fdocid%3D-5629273206953884671 tells us that the appropriate link to the .flv file is http://vp.video.google.com/videodownload?version=0&secureurl=uAAAAAyr3sxMNkqozoBkfokEDUfpW3cQVL7NG8w0Iw-Hnmxyi2gdSouUGo8mbWy6_efOtaii3y5-8OWHk5onBABjamiov-RdQq8xfLlGY6F-xPIqtzrytBamg7t3zbgG-qtfH4B5tiyZJS6aB4r14N8uF2al00ZUw0Lxf6K-w7PYv2ylbKLpy_I4Idh0GUYLPxqyRmq_9zhd8TC3QGPBj_LkJcSqYIkH2tlMDvTbQA7UinRNSWr0oYmgcDuCn9jc7zxFDw

And one can then wget or download through Firefox without a problem. It would be a good thing if clive could be fixed to work with pages like these and not falsely report that there is nothing to download.

(This is strictly speaking probably a feature request as I have no evidence that this example link used to work; but I see no option for enhancement or feature request, so...)
