Forward/rewind buttons not working if playback quality is set to auto/top available

[HackerWolf]

Hello there! As per title, Tizen client has forward/rewind working only if the playback quality is not auto or top available. On a bunch of 1080 H264 videos, only if playing them at lower resolutions (720 - 480) the mentioned buttons work properly; instead at 1080 results in the following behaviours:

• in the Tizen Emulator (running on Ubuntu 23.04 and targeting T-samsung-7.0-x86), the buttons simply do nothing;
• on a Samsung The Frame 55" 2022 TV (QE55LS03B - tizen-6.5 if I remember well from what I saw in Tizen Studio), pressing the buttons get the video to start again from its beginning.

Please note that:

• Jellyfin Server (v. 10.8.10) is streaming via Internet, not in a LAN environment; it runs on a Ubuntu 22.04 ARM64 server (bandwidth 2+ Gbit/s symmetric) and it's located in the same country of the clients, usually replying in less than 30 ms;
• the above mentioned Samsung TV is connected to Internet via WiFi on a FTTH 2.5 Gbit/s connection (at least 500 Mbit/s always to the TV);
• the issue is not happening via Web Player (tried both Chrome and Firefox);
• the same issue manifests in the Android TV client too (yes, I know this is not the repo).

I can't provide at the moment any logs or screenshots but I can do tomorrow or in the next days. Thank you in advance!
