This is an error of YouTube, or your ISP (if it intercepts YouTube requests). What would you expect? Should we maybe clarify that in some way beside mentioning it's an HTTP error?

[sirinath]

I have noticed these errors some times happen:

1. In play lists with deleted or videos which have been made private
2. If you have partly watched the video in the browsers (also if you do not specify -f generally these are downloaded as flv. I am not sure how this is the case. Might be coincidence.)
3. When you try again and again the error keeps happening in the same videos but they eventually complete but most of the time only few bytes are received.

Is it possible to give more info to see if it is a ISP interference or a YT error and what the reason behind it?
