Same media files url

When I add a Tudou Media Url. it always tell me the uri is already exist.so if i have a lot of medias in libraries its very difficult to find the existing file.

With this feature we can find the existing file and update and we don't need to create a new one.

Feel free to let me know if you would have any questions, comments or concerns on any aspects of the discussed feature, I would be glad to explain in more details.
Thanks very much to all, in advance, for your comments, feedback, testing, reviews and reporting.
Cheers!
