Ok let me explain why convertion sucks when you switch from revshare to PPS 
 
As you know, most of the people don't join right now for a site when they visit it.  Approx 50% of the surfer comeback later when it's a better time for them to join (wife not there, membership at another site expire, etc etc etc) . Since you can use both per signup and revshave programs at the same time into our system, all the old surfer you sent to the site still have their cookie set for partnership program. So what you are probably experiencing are hits into your PPS and sales from partnership. And since both are track appart, this is why the ratio of the PPS seems to look bad.  But don't worry,  it will return to exactly the same convertion with time $¬)
We don't and we will never shave. We are working on upsales and way to improve tracking so you can make even more money out of the same traffic. Our goal is to make more money into your pocket so you'll send more traffic our way and  this is how we all gonna make more money.

Chowda - we are working on the slow video problem. It's cause by our new security system.  We are adding more servers this week to fix that.
