2015 LG TVs, i.e. UF series have WebOS 2.0. UH are from 2016 and have WebOS 3.0. WebOS 3.5 is introduced in 2017. You probably have firmware version 4.x.

Why don't you download the firmware from UK website and update manually?

You are saying that other people have firmware 4.0 or 5.0 for SM8200?

It is not possible.

Yes, that is it.

Yes, that is it.

You need optical (toslink) to RCA adapter.

Videos recorded by TV are encrypted, and may be viewed only on that particular TV. You probably need better settings for your USB video capture card, or get a better card. Try to Google for VHS capture settings. Long time ago I was successfully using some Terratec TV card to capture old VHS tapes. Also, some digital cameras have A/V input. Here I have found a list: http://www.4kam.com/camcorders_with_av-in_av_input.htm

You probably need CI module and a smartcard from your cable/satellite TV provider.

There is a topic on Hotstar application. According to the information on Zee5's website, there are only Android and iOS applications available. You should ask Zee5 to create a WebOS application.

You cannot do that. There is no internal memory available for user files.

You should try some other DLNA server. For example, Plex, Serviio... I am using Plex server on my NAS, and XPlay application on TV. With this combination I can use subtitles in different languages if I name files as follows: Movie.mp4 Movie.en.srt Movie.de.srt

Unfortunately, more memory cannot be added.
