New OLED65G1 DLNA client much slower than DLNA client on OLED55B6T

[Nick Payne]

I run a media server using Serviio on a Raspberry Pi (several thousand files just organised by folder structure), and I use the DLNA client built into WebOS to play the files from the server. For the past five years I've had an LG OLED55B6T, and due to a bit of burn-in on the screen, I've just replaced it with an OLED65G1PTA. One thing I notice with the new set is that it's much slower to navigate through the folder structure on the media server to get to the file I want to play. The difference seems to be that the DLNA client on the old TV just shows folders with a generic folder icon, whereas the new one wants to thumbnail each folder that's visible on the screen before it will allow me to continue. I haven't found anything in the settings to stop this behaviour - you can choose to display the folders as a grid or list, but either way it still tries to thumbnail each folder.

As an experiment I installed Kodi on a Chromecast with Google TV that I have attached to the new set, as it can also act as a DLNA client, and it is also much faster to navigate through the folder structure on the media server. However, it has the drawback that if I stop watching a video part way through, it doesn't remember the point I was up to when I restart watching, whereas the client in the TV does.

Any suggestions on a possible fix for speeding up the navigation?
