I was recording The Andrew Marr Show on BBC1 HD this morning, and whilst watching it, the picture and sound froze and the scrolling text (as i do not have Red Ring running currently) stopped scrolling, and nothing worked. I tried all the buttons on the remote, all buttons on the box itself, but it was simply stuck! I had to switch off at the rear, and then back on and play the recording from the start (it was still recording the programme when it froze, so it failed to finish recording to the end). However when i fast forwarded to the point it froze and pressed play, it got to the exact same image on sceen, and froze again! However as I had gone past that point and rewound to just before it, I had to switch off again, and then fast forward past the point that obviously has the issue and play the programme from there. My question is simply can i find out what caused the box to freeze in such a dramatic way when simply recording a programme, and seeing as i have still got the file, will the CF diagnostics help me at all?
