This is a new one, and I'm wondering if anyone else has experienced anything like it. I've had the Sci. Atl. 3100HD box for about 18 months now. It's connected to three different sources: (i) HDTV; (ii) TiVo; and (iii) a Panasonic DVD recorder. Never had any problems with it until recently. Several times in the past two weeks, the box has simply "frozen". The behavior is almost like a computer that's locked up and needs rebooting. The screen is frozen in a kind of mushy video snow (sometimes pink, sometimes green) and the audio goes to static. The power on/off switch has no effect on the display; the box won't power off but just keeps sending out the same fried display. Oddly enough, the HD channels continue to display accurately -- but no other channels, even through the HD output. Unplugging the box and waiting a few minutes before plugging it back in always brings it back to normal operation -- just like a computer that needs a complete reset. Has anyone seen anything like this before? Is it an indication of something in the box going bad, or could it be an effect of some signal that Time Warner has been sending out (their digital channels have been particularly bad lately)? All thoughts and speculations welcome. M.
