Advertisements after receiving the new summer update yesterday, my tivoHD with dvr expander operated properly for just an hour or so. the box would restart and hang on the first powering up screen and stay there. forcing a reboot just repeated the process. since i had some issues seemingly related to the expander, i powered the expander down, and got the blue screen on restart saying the external storage device wasn't found. after 3 unsuccessful restarts failed to get me back to normal, i opted to divorce the expander. now, the unit is working flawlessly, just like my other tivoHD that does not have an expander. so, i am hoping this is a known issue, and they're working on it. before 9.4, at least i was able to use the expander, with only occaisional lockups. i was then able to get the box to work again after a forced reboot. this is very annoying, as i paid over $200 for the expander and now it may just be another brick like my hd dvd player.
