In recent weeks I have had to reset the Sky + box multiple times. It's done odd things like not pausing on playback; the occasional arbitrary long recording (1000 min and more) of a 90 min programme; sometimes thinks it's 100% full. I use subtitles, these sometimes disappear temporarily, sometimes they are there till I've fast-forwarded a couple of times, then they're gone.
It's currently rebooting, I had to watch yesterday's My Kitchen Rules Australia including the adverts and am hoping it captured today's episode OK.
It's an old box (with some recordings I'd like to keep); but some sky forums seem to indicate there might be software issues?
