HiassofT is right: If a too small OS partition is your problem, you don't need to buy an SSD. Just enlarge the OS partition with an appropriate tool like GParted. I suggest to give 1GB to the OS partition (LIBREELEC / OPENELEC), and assign the rest to the user data partition (STORAGE).

So for me to update and get a bigger one (the one inside is 40gb Intel SSD 2.5" drive) i have a ASUS S1-AT5NM10E Barebone for the task. Does any new SSD work?

Sure, copy from HDD to SSD, and LE should work.

If set 24Hz in the system display settings (as I wrote above) there really are no problems..

Maybe you can keep the original HDMI mode, and just switch de-interlacing off: Click!

In kodi: Settings/video settings/Deinterlace method Off

Interesting solution, thanks!

Always the same problem. The problem exist also with VLC, then is it more a system/hardware problem ?

Maybe your TS file has errors, and some players auto-fix those errors.

Do you find a solution ?

Please try this advancedsettings.xml:

<advancedsettings version="1.0">
    <cache>
        <buffermode>4</buffermode>
        <memorysize>7000000</memorysize>
        <readfactor>4</readfactor>
    </cache>
</advancedsettings>

The fact it works on my Acer monitor leaves me scratching my head and really bummed the Pi 4 is having these issues.

Very rare, but possible. If my last advice doesn't work, I would go for a replacement.

One final thing, before I'm running out of ideas. Try different color spaces by editing hdmi_pixel_encoding at config.txt. Some monitors use YCbCr instead of RGB. Good luck!

Try this config.txt (enforces CEA mode 16):

gpu_mem=320
force_turbo=0
hdmi_ignore_edid=0xa5000080
disable_overscan=1
framebuffer_width=1920
framebuffer_height=1080
hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16
dtparam=audio=on
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

Those settings work for many users with older monitors.

Do you use HDMI 0 as RPi's output? If you use a case with HDMI wiring, remove the case.

PS: Did you already tried hdmi_safe=1 at config.txt?

Nuke Windows, and use LE only, or dual-boot with a standard Linux.

Sounds like a plan. Take into account that HDMI data rate is higher on RPi4 (compared to your old RPi3). So eventually you have to get a new HDMI cable, which is conform to HDMI 2.0 or 2.1 standard (ready for 4K data rate).

Then do the next step, and remove (backup as before) the complete userdata folder. It will be re-created after the next boot with default settings.

yes, same buffer timeouts on sdcard. But shouldnt the problems occur at some point on every libreelec rp4 installation?

Yes, we already had other reports about AAC issues. Another theory is that the RPi4 data bus is too slow to handle AAC. Try this trick, which will set some data bus resources free, and hopefully solves your issue.

PS: I just found this buffering settings, which you can try, too. I'm optimistic that one of those two approaches will work.

The buffering options are active on A/V playback, WiFi or Ethernet doesn't matter. Try to play the same problematic file from USB stick to rule out slow WiFi.

Understand. I move this thread to the add-on sub-forum, because that's the place of those dev's. Most add-on dev's are at the Kodi forum, so it could be a good idea to ask there, too.

Looks line an AAC buffering issue:

Option a) Activate pass-through at the audio settings.

Option b) Use advancedsettings.xml (chapter 2.9.5: cache) to edit buffering.
