compression I noticed that your site really goes for the "classic youtube" feel
while the format for the site seems a bit out dated I see where you are coming from
however there is a difference between imitating classic youtube and being classic youtube and you guys are defiantly going for the later.
Allot of the video compression that was done then was acceptable because no one knew it would get better but today compressing your videos as much as you guys do is seen as low quality to the point of being unacceptable.
Is there anyway you guys can fix this? I would love to see a site like this thrive but there is no way it can if the videos are being downgraded as much as they are.

HTTP error 500 constantly clearing cookies solves this but its pretty annoying when going from account to account

Audio Videos Instead of having to upload a video with music, why not just allow the user to upload a sound file (like an mp3) and a title image to go with it? It would allow for much higher quality music videos and they might be smaller too.

Multiple thumbnail choices Instead of the already chosen one for your video, add the ability to change between 3 or 4 different thumbnails the website screenshoted from the video
