Even though I am not yet using this myself, I will add in that the price is very reasonable. A similar script that plugs into the clips hare clone sells for $30 - so Galnet's is half the price.

I dont know anything about his code, but the other one is also an exact copy of youtube's clone, which is probably illegal. So I suspect Galnet's is probably superior on that level as well.

I know it is probably tempting to buy it and use it on every site you have, but what's another $5 per site? It seems to me that it's a small price to pay to operate honestly, legally and legitimately.
