Although I mainly use this to view directv while traveling, it does other functions on which I haven;t scratched the surface. Here;s how well it workes for me. I live in Minneapolis, but am spending a month or so with my parents in ND to help clean up after the flood here. My vulkanno (yes, that's how it's spelled) is connected via component to my HR20-700. the connection to my home router is via WI-fI, and only wireless G! (I do have a fairly good home upload speed of about 2Mbps.) In ND, i have my desktop fitted with a wireless adapter, as the router is across the house. This too is wireless g, and only DSL with a 4 Mbps download. ,The result is a virtually studder-free 720x480 picture. i know they are using codecs such as h.264, but it runs circles around my slingbox solo. The best part, it was $99.
