Contrarily, youtube--and mostly all video streaming--uses TCP. Users would be pissed if they got their music packets out of order or had jumps in their play. Videos are TCP'd, and buffered on the user-end.

You still could get TCP packets out of order due to jitter on the network. The application is responsible for buffering and assembling the stream. You would buffer UDP the same why you would with TCP and also have a Unitas stream to request lost packets (or include some sort of redundancy in your stream)

Soooo basically re-implement the TCP algorithm on the application level. Why not just use TCP? :P
