Generally speaking, trick mode is FF/Rewind. The only ethernet advantage being offered by the 441 software release is that you no longer need a phone line connected to your receiver if you have the ethernet port of the 622 connected to a network with an internet connection. The 622 will connect over the internet to Dish's servers to "phone home" instead of making a POTS call over the modem. The rumored features possible with the ethernet connection (in a later software release) include configuring timers remotely, and either downloading or streaming PPV content. The ability to transfer content from the 622 to a computer for viewing or burning to DVD? Not in this lifetime. The content providers would never allow Dish to enable that kind of feature.
