Same problem here...frozen video, but audio continues on...no channel change possible. Box still responds to "Settings"/"Help"/"Restart". Happens about once a week to our DVR ( AX013ANM), and occasionally to our extra room small boxes (CXD01ANI), but I think technically that the DVR/main box feeds("IP tuner?") the extra room boxes anyway. A recent install (2.5 months ago), so signal should still be OK. Also, do the "system restarts" that happen every night about 3am really deliver fixes/updates or is it mostly a "preventative maintence" reboot? Is there a listing of current software versions for the various Comcast boxes to see if mine is up to date? Thanks.
