Reboot Affected Signal Strength!

[Black Hole]

I was watching Dave perfectly well, but the machine needed a reboot because the schedule had gone AWOL (again – this is the third machine, and no I didn't think to look at previous advice).

After the reboot, Dave was all blocky. Hard to believe it's a coincidence.

Tut, tut!

Depends what you're watching on (Ewan) Dave. HIGNFY often goes blocky during and just after captions on the orange/red newsprint type background.

Edit: Haven't noticed other programmes being blocky, or HIGNFY on Dave ja vue exhibiting the same problem
