Glitchy recordings from USB disk


vinnieb

Question

Hi,

I've recently purchased a LG 43UK6300PLB, which by and large has been excellent! But I'm having problems with recording to USB. So far I've tried a 500GB drive I had spare, but its probably 7-8 years old, and I've tried an SSD as well. Tried the 500GB in an older USB2 external caddy and in a more recent USB3, and the SSD in the USB3. Both were formatted to NTFS.

When I come to watch the recording, I get what looks like signal breakup where I might lose a second or so of the recording. Its not constant either, there might be a 10 second period where the quality is really bad and broken, and then maybe a minute of it being OK.

I've tried the USB3 caddy with external 5V power added in too, 2A supply.

Same problem happens if I pause live TV, and then unpause it a little later.

Normal TV picture quality is fine, I've got good signal here and never see this on normal viewing.

Wondered if anyone had suggestions? Is it worth trying a USB stick instead? Running out of ideas with this one.

Thanks

I get exactly the same issue on a 6470 normal viewing is fine and never breaks up. But recordings via USB (I have tried 3 different disks including a SSD) are always glitchy. I have recorded a live broadcast and watched it with no glitches and then played back the recording and it contains glitches. Happens on both Freesat and Freeview.

If anyone has an ideas please let me know.

I followed up with LG tech support a couple of times, they suggested it was because the signal strength (if I remember right) was too high - they wanted it to be something like 75% to 85%. So, I got this down to 80% but made no difference for me, but maybe worth checking.

It's strange as I guess it must work for most other people, but I tried a bunch of difference devices, and even benchmarked them on a PC, finding the IO performance to be way better than what HD recordings should need. Having said that, did seem worse for HD channels than SD, which made me wonder if was data rate.

      Hallo, I bought a 55un74006LB smart tv in Italy. It seems not to have usb recording capabilities, according to the information on the italian website, but the UK site declare it has. I think it's the same product with the same functions, so how can I turn the live tv and usb recording on? I think I found the options in the service menu but I cannot change the values. Any suggestion?

      Apple has been rolling out the Apple TV app to many different platforms, including smart TVs, games consoles, and third-party streaming devices like the Amazon Fire Stick or Roku streaming sticks.
      In a slight twist, the company is also launching a ‘Apple TV+’ app for older LG webOS TVs. Update: The TV+ app is also now available on older Samsung smart TV models.
      The launch was first spotted by FlatpanelsHD, and later confirmed by an LG support document.
      The standard Apple TV app is available on 2018 and newer LG webOS TVs. This special Apple TV+ app is targeted at 2016 and 2017 models.
      Although the name and logo is different, the actual app experience appears identical to the TV app — except that you can only watch TV+ content. The Watch Now and other iTunes Store tabs are simply missing.
      Somewhat comically, that means this app has just three tabs in the top navigation — Apple TV+, Search and Settings. It also means that the Up Next functionality previously found in the Watch Now tab is now awkwardly located as an inline row at the top of the tv+ page.
      It is true that many proponents of Apple TV+ — including me — have wanted less focus on the iTunes Store in the TV app in order to focus on the content available to us with the subscription, but this particular stripped-down incarnation is not quite what we had in mind.

      Model: 42UB700T-TH version 03.02.25. Has not got any software update since  3-4 Years - What a mess...…
      This TV is just a random box now... Once purchased this model - new version from LG was introduced; making this just a playing box...
      None of the recent OTT's can be installed..
      We need a fix or else some solution to it.
      Its really a disheartening experience after being loyal to this brand in any appliance we purchase.

      Hi
      I have a Smart TV OLED55B16LA with Satellite and CAM Card.
      I can record Satellite programs, but it seems it only records the "default" language. When I play back the other language is lost.
      Is it possible to record all languages, or at least decide which one?
      Cheers

      Hi I have a LG Smart TV (OLED55B16LA) and started using the recording feature.
      I would like to replace the USB HDD with a bigger one, so I have copied all the files from the old one to the new one.
      But when I put the new one in the TV it does not recognise it as a recording, it lets me browse the content. but of course being scrambled it is pointless.
      Is it possible to move all the recordings to a different disk and use it in the same TV?
      Cheers
