I have a recording where the fast-forward/back buttons refuse to work ... The buttons to skip forward/back work OK and moving the cursor along the play time-bar works, but fast forward gives the error symbol (circle with diagonal line). As far as I can see it's only happening on the one recorded program. Any ideas what's caused it, or anyone else seen this happen? I've tried a full reboot but this made no difference. It's an episode of Million Pound Drop where fast forward is needed to avoid Davina's incessant, repetitive chatter! Other recorded episodes seem to be fine.
