We have had our UE46F8005 for years and used an external HDD to record and time-shift TV programs on a weekly basis. The firmware is updated (at least when I checked last month)
When we want to see our recordings only the first 3-5 minutes of the TV program is shown before skipping to the next recording (or exiting if it's last recording on the list). The recording is listed with the full time so there is no indication that the recording was prematurely abrupted. Also we get the notifications on the screen when the records starts and stops and that is as expected.
