Have just started using my smart tv as a freeview HD PVR.

I seem to get spats of digital breakup, despite having a strong signals of:

Signal strength: 99
Quality: 100

I have a small rf cable attached to the aerial to extend the length to reach the tv, perhaps this has something to do with it?

I didn't have any breakup when the same aerial was connected to youview - only a slight glitch if a plane flies over.

Could be too much signal.
Have a look here http://www.ukfree.tv/fullstory.php?storyid=1107051892 which says
"The signal strength should be around 75% - more than this indicates too much signal"

It could be too much signal or the RF extension cable.

As for the extension cable.

If it is a cheap and nasty poorly screened cable it could be letting in who knows what nasties. Something that has been posted here a few times is interference from HDMI cables when the two are in very close proximity. Separating the cables physically has been reported as having the effect of reducing any interference. Not seen it myself in my own set-up so can't comment on how real this is, but might be worth a punt, only wastes a few minutes of your time after all

If it is possible to plug the aerial lead into the telly without the extension, even if only temporarily, that might eliminate the cable as the problem. Or swap it out for a decent properly screened cable and see if that makes any difference.

I'm getting this recently on a Panasonic 50" TV, for Freeview HD pictures only. I haven't had it at all before the last couple of Freeview updates, so something's up that's out of my control. It only happens for a second, but when it's during an intense drama like Utopia, for example, it really screws with the atmosphere.

Too many HD channels crammed in?

The number of channels has little to no bearing on signal breakup. It just affects the picture quality due to lack of bitrate.

Much more likely is that there is some external source of interference causing the glitches. Dodgy electric switches are a prime cause. If the switch contacts arc all sorts of garbage can be radiated down the mains or through the air. This can easily cause interference with TV reception.

If it happens more on the recently added HD channels (BBC4 etc) that may be more noticeable for a number of reasons associated with how that mux is transmitted and received. Often that means a weaker signal than the other muxes which may make it more prone to interference.

Short bursts of interference might be due to some electrical system switching on or off. If so you may be able to spot a pattern when the glitch occurs. One thing my mum had with an old Goodmans box years ago was it would mute the audio for a second or so every time the fridge door was opened or closed and the light switch operated!

It's happening on existing HD channels as well, but only HD. If I'm watching the news then I'll just flick back to SD if it starts becoming a problem, but a drama or film, I'll want to watch in HD, especially in the case where something's made in DD5.1, which includes Utopia.
