I've recently noticed problems with the aspect ratio on some Freeview channels on my Pioneer DVR-540HX [Hardware version 410, software version 101j].
When I switch to an affected channel when it's showing a widescreen programme, the picture is initially correctly displayed in widescreen format but after about a second, it switches to a 4:3 aspect ratio with black bars down either side. When it switches, the picture is not horizontally squashed (that is, the sides are chopped off instead of it being horizontally compressed).
I've noticed the problem only seems to affect channels on multiplex C and D.
Channels exhibiting the problem: Sky three, 4 Music, Dave, Dave+1, Film 4, Sky News.
Channels that are okay: BBC1, BBC2, ITV1, CH4, Five, ITV2, BBC Three, BBC Four, ITV3, Ch4+1, More4, QVC, BidTV, ITV4, E4, Five US, FIVER, BBC News, BBC Parliament.
Other channels might also be affected, but I've not been able to confirm (e.g. because they were transmitting 4:3 content or were off air at the time).
A few weeks ago I also noticed that 4 Music was transmitting a 16:9 picture but horizontally squashed in a 4:3 aspect ratio.
I've tried rescanning the Freeview channels.
I've had my DVR-540HX for around two and a half years now and I haven't seen this problem before.
The programmes are correctly shown in widescreen when viewed via my Samsung TV's built-in Freeview tuner.
Does anyone know what's going on please?
Thank you.
