Hello, I have a Sony NSZ-GS7 and I have a slingbox which I have purchased and have it connected to my tv in Japan. From my computer, I can log in and have the remote control appear on the screen so I can pretty much do everything with it... but I rather watch it on my TV since the screen is much bigger.... However I don't see some of the buttons on the on-screen remote control such as the power button, dvr, etc.... there are some blank ones. so if the slingbox is off, I would have to use my computer, and turn it on, then re-connect from my tv.... is there a way I can configure the remote on my sony nsz-gs7 device and add some function to the blank buttons? Thank you.
