Youtube also has the advantage of discoverable. The downside is that you don't "own" the comments. If someone puts in a bad comment everyone else will see.

I'll give SublimeVideo a look.. seems interesting

I tried a bit SublimeVideo, it seemed a bit slow in mainland China, not so sure about this, but clearly the SublimeVideo website takes ages to load here.

I finally gave it up.

SublimeVideo is what RailsCasts using now. So you should be very familiar with how it works, :)
