Recorded programes disapeard from memory for several hours. Tried switching off and on, later re-appeared. Wow. Internet site poorly referenced for support on model of box. Internet site for latest firmware does not exist. Contacted Humax for latest firmware, will try downloading again. Connected to internet on broadband-either box or internet site kept stopping playback with error message. No idea what happening. To early to give indepth review, only had 1 week. But it does keep a clear digital recording like a dvd with the convienence of a video player. I like so far.
