I have't got a variable gain amplifier, but I have got a 12dB amp and a variable attenuator, so I can play about with those to see whether they make any difference.

One of the things I'm planning to do (when I can interrupt SWMBO's viewing!) is to swap the HDMI lead for a SCART. Then I can see immediately whether there's any change in signal quality.
Both the TV and the Humax are manually tuned to the muxes on Sutton Coldfield - and there are no 'strays'...
I take your point, but the SYMPTOMS are exactly the same - and nothing changed by swapping one box for another - which rather suggests that the root cause is external. But finding what might have changed about four months ago - to start upsetting the Humax without affecting the TV ain't going to...
Can I say that I very much appreciate all the responses which people are making to my posts. I apologise if I sometimes appear to dismiss helpful suggestions out of hand - that it not my intention. But I am trying to home in on those things which seem most likely to have an effect.

OK, it's on my list of things to try. Would the HDMI cable radiate RF when the TV isn't on? I ask because the breakup problem first occured on recordings made while we were away from home, with the TV firmly off.
The HDMI cable which I'm using is the one supplied by Humax. FWIW, I'm not having...
I'm not sure that a passive splitter would be a good idea, since it would reduce the signal level. As a result of a suggestion made in another forum, I have removed the RF between the Humax and the TV - with no effect whatsoever. It means, of course, that I can no longer use the TV's tuner as a...
In that case, it doesn't seem likely. As I said in my previous post, the problem first manifested itself on some recordings made while we were away from home, with the TV firmly switched off.So the HDMI cable certainly wouldn't have been actively doing anything at the time.
It's Sutton Coldfield. A fairly substantial Group B aerial on the chimney feeds a distribution amplifier in a first floor bedroom/office. One of the outputs from that goes to the Humax and TV in the lounge below.
UPDATE. After a fair bit of persuasion, Humax have replaced my HDR-FOX-T2. Initially they said it sounded like interference from other transmitters, and required me to do a factory reset and manual re-tune to make sure there no duplicate channels. I did all that, and it made no difference, so...
Many thanks for that. Using Ext2Fsd, I can now access the files on the external drive without needing to take up space with copies on my computer's hard drive.

Many thanks for that. It has got me a BIT further forward. My version of Nero (can't remember its history!) reported 'compatibility' issues and refused to do anything. So I downloaded and installed ImgBurn - which succeeded in writing to the DVD, and all seemed well until the very end of the...
You're absolutely right of course, but it seems to me that using a DVD-R would give it a bit more "permanence" because USB sticks tend to get over-written - sometimes by accident!
I've actually got the files on a 120GB hard drive - rescued from from old PC and mounted in a USB enclosure. This...
Or, for HD, use Foxy first and then copy to a USB drive and then FTP to a PC.
That's the easy bit! It's after that that I struggle.
Humax are about to replace my HDR-FOX-T2 after a lot of tuner problems (discussed in an earlier thread). Although we mainly use the T2 for time-shifting...
So what are you going to do about it? Is it still under warranty?
I'm wondering whether I have a related problem with my HDR-T2 which is just under 18 months old, and thus still under warranty. At first I thought it was temperature related and only occurred when the house was unoccupied for a...
Fair enough - but I was responding to a post which said that I couldn't compare the daisy-chained TV's signal strength with that of the HDR-T2 because of the intermediate amplifier. I wonder what would happen if I daisy chained a second HDR-T2 rather than a TV. Would both T2's then report the...
Yes, I can't see that it do any harm! I'll try to get some screen shots when it's playing up, by way of evidence. I'm going to be away a lot, on and off, during the next couple of weeks, but will take it up again when I'm back for a bit.
WT
Are you saying that the Humax delivers a BETTER signal out of it's daisy-chain port than it uses for its own internal purposes? I suppost that I should perhaps unplug the aerial lead from the Humax and plug it into the TV in order to do a direct comparison. But I doubt whether it make any...
OK, a bit more meat on the bones . . .
The problem tends to occur in the early evening, and then sorts itself out by bedtime. It seems to be confined to the COM muxes - the PSB muxes seem to be ok.
On the PSB muxes, Signal Detection shows a strength of about 50 to 55% and a quality of a rock...
