Yes, before placing the order I did a through research and both the models are for Europe only with 220v, just for specific countries within the European Union the 824 is sold. This too is made in Czech Republic.
Also, I checked the firmware between the two models, both are same for Europe specifically and the latest one is released on 19th June 2024 version 1.82 which is the only released after year 2023. Since the player was launched in 2018 so can't expect much improvement here. But I'm happy that Panasonic is taking care and have released a new firmware for newer formats or compatibility with newer BDs.
I've also bought a 8k certified 48gbps HDMI cable from Honeywell for connecting the Blu-ray player to my LGC3 for the best picture quality (HDR, DV etc) and an already using 18gbps cable (which I believe is more than enough) to Denon AVR for audio.
Now just waiting for it to get dispatched and arrive soon. What's with yours, dispatched? When is the arrival?
