That is the only issue with the s905x. Should have charged 50 instead of 40. For the clip that you just couldn't get enough bandwidth for, I have something to try. Have you tried mounting the NAS so the OS handles the network stuff, instead of Kodi. I had a lot of troubles with my box and larger files. But it was always almost enough, so I would keep struggling with it. Haven't had a single stutter since and I play some huge files. I wish I had done it months ago when it was suggested.
R4w has been suggesting this and I wish I'd listened sooner. It's a mount command like here:
If you have tried this and it's too basic for you, apologies.
8.0.1j seems to have everything perfect with my box as well. Smooth as butter playback in all rates, audio files, and dts-hd trueHD. I have to keep testing but you've really made this box a winner kszaq, Thank You!
Same for me, I connect to my NAS using WiFi and since mounting the NAS at the OS Level, I never had any issues, even on 50 Go HDR 4K files...
