We did a large (14 hour) manual recording and can't seem to play it back. It says it takes 4% and is 35Gb in size. But, on the Play/Delete/Related/etc screen, when pressing Play, the screen briefly clears and then comes back to that screen. No error message, just nothing.
Thinking back to the last couple of Olympics, we recorded several 6-8hour programmes and they worked fine. But otherwise... assuming you've done the usual box reboots, trying smaller recordings etc etc, I'd only suggest what danny has come up with.
Thanks for the thoughts, I don't know that it's to do with that, as I'm sure I have bigger files on my laptop. I'm only guessing, but it's most likely to use ext4, which can have files into TB sizes... Also, it says the file is that size, surely if it was too big, if would have truncated the recording as the file hit the maximum size?
