Professional video hosting site

[soulscriber]

I am looking to develop a microsite that does video hosting. Users need to be able to upload videos, rate videos, and it needs to be able to handle a load.

I have heard this should be coded in jsp.

Does anyone have any suggestions? Please keep in mind that I am aware of phpnukevideo, mediasitescript and others. I am worried these will not be able to handle a high traffic load. Does anyone have any ideas?

Thanks.
