Capture "long" non-live YT streaming

[ycrcb422]

Trying to capture "longish" youtube video that is likely being streamed, but is not a live stream. Video Download helper does not recognize and as such will not "download".

http://www.youtube.com/watch?v=Yg3YDN5gTX0&hd=1

So I tried several of the URLs presented in the Net web console, but always get:
"Invalid data found when processing input" from ffmpeg (see a full output at end of post)

FWIW, I used the same methods as described in this thread: http://stream-recorder.com/forum/cap...ffmpeg+youtube

But have not had success yet.

Any insight?
