I plug my hauppauge in and i assume the hauppauge is working as intended, however eyetv instantly lags, stutters, then stops working altogether and to top it off it shuts off the usb connection to the hauppauge once it breaks. Im on mac sierra, i paid for this and theres no other way to stream my hauppauge live on my mac, this is very frustrating and i really would just like a refund i think..
