The less you convert a file, the better it will be. Most video
compression schemes are lossy (data is permanently discarded), and
compressions upon compressions (video to VOB, YouTube's conversion to
Flash or webm) can produce nasty artefacts. Put another in the middle,
and you multiply the problem.
However, it is possible that very good compression in the middle of that
(i.e. one that's not very destructive to the data) may not be
noticeable. Especially when you consider the small picture size that
YouTube has for the video.
The same goes for audio. Some YouTube clips sound like a detuning
shortwave radio, played back over a chewed audio cassette from 1977.
