Yes-- after software upgrade, started experiencing both lockups and reboots.....
-- Only had 2 true lockups-- where the only out is to pull the plug .......
-- Several other soft lockups-- no response to any command, but after a while, it goes through a reboot sequence
-- Almost daily reboots ..... always when changing channel, switching tuners, trying to bring up the guide, or going to Now Playing. Happens most often close to time changes (top or bottom of hour). Even had it hang with menu overlaying programming....
-- Rig is stock HR10-250. Both OTA and D*.
-- Of course, the anoying audio drops ..... don't know if that is rig or from OTA stations.....
