Over the last month I've had several 622 crashes with the following symptoms (while watching a live sat program): 1. Picture freezes 2. Screen goes black then all blue 3. Black screen once more all the lights go off 4. "Searching for satellite" screen comes up and freezes. (green/yellow lights back on). There is no "progress" to the search (1 thru 5), and the "help button" is non functional. Perform soft reset with power button. Hard drive screams for about 30 seconds; all the lights blink; back to "searching for satellite"screen...which might be frozen again or may actually - but very slowly - begin showing progress. Sometimes take two or 3 resets before we ever get back to an actual picture and sound. Anybody else had this problem?! Any fix or any idea what's causing it?
