I got my HD finally installed yesterday. However, I have not been able to experience the glorious picture yet. It is still hooked up to my SD tv right now and the picture quality on the HD channels is a lot better than the standard channels. However, I will be hooking it up to my LCD tv tomorrow. Anyways, my first question comes after noticing I of course got a new "Factory Reconditioned Unit". So anyways I can hear the hard drive being accessed constantly and is very noticeable when recording a show or fast forwarding. Is this normal and should I be concerned? I am used to my Tivo an all I ever hear from that is a little, quiet hum from the fan. Second I read something about hooking this up to the internet for VOD. I have a wireless Adapter that I can use. Is this worth hooking it up? I really have not heard a lot about Directv VOD. Third, I just noticed that the internal temp according to the info page is 122 degrees. This seems hot. Is this normal? Fourth what kind of cool features does this unit have? Also, my wife is keeping her Tivo upstairs, but will also be using this unit. Is there a learning curve?
