A few years ago when I moved into my current home my old pvr didn't have much luck finding channels in a rescan - I was told to do a factory reset, and then a rescan. Sure enough somehow this then found much a stronger signal than before. Recently (since digital switchovers I'm assuming) I've practically lost ITV, Channel 4 and five (though not ITV HD or 4HD) on my lounge TV, using the HDR-Fox T2. Rescanning doesn't help, and I'm wondering if it would help to factory reset the box first? Most importantly I want to check that factory reset won't delete all my recordings? The signal did go about the same time as I changed the way my aerial cable ran to the telly, but I've run a new cable and it's just ass bad, so I think it must have been the requests that have come on screen about rescanning for channels.
