@Sesto2k ok would you have the possibility to try with an other hdmi cable or on an other tv ?
I would have to buy a new mini HDMI cable. Basically mine works though. I can try to connect another monitor, yes... just have to get one from the basement right away xD.
Give me a little time...my son has to go to bed first 
I tested another Monitor (Dell)...same behaviour:
You can see, that the Monitor turns on with it`s "grey" instead of pure black screen but no video appears...then the visible bootscreen follows and the system starts. After that everything is normal like in 8.1.1.
Here is a Discord link from my post, how it looks now with 9.0:

And here is my post as it ran before the update, i.e. with 8.1.1:

By the way: Nasuku is my Discord Nick....;-)
@Sesto2k If you wait for Recalbox to fully boot, then connect via ssh and run /etc/init.d/S06splash start do you see a boot video then?
Thank you all for your help 
Finally i found the issue by testing Recalbox with a Mini PC instead of the RPI4.
It first booted without any videos, too.
Then I went according to the exclusion principle because the video was suddenly played after only the USB stick with the Recalbox image was connected to the mini PC
Then i connected everything back to the RPI4. No Video...
The solution so far:
If everything is connected except the both Dragonrise USB Encodern then the bootvideo plays...on pc and RPI4.
The problem is caused by the encoders !!!
As far as I know, boot videos can be skipped with 9.0. Can it be that some function is activated by default with this encoder type so that the boot video is thereby skipped?
What can i do now...i have no idea but good to know who is responsible for the problem....
@Sesto2k Interesting. There's a commit from 4 months ago with the message:
feat: allow user to skip boot video by pressing any key even gamepad
Could the Dragonrise controller be sending button presses causing the boot video to be skipped? Have you got the turbo fire or auto fire feature of the Dragonrise turned on?
If the Turbo Fire function was on, I have now disabled it. I simply connected the two contacts of the clear switch with a piece of metal and then pressed an action button. But: Still no boot videos
I honestly have to admit to the MPV story that I don't know what to change, delete or do anything else. Unfortunately, I'm not a programmer and that goes really deep into the matter.
@poppadum said in Bootvideos don`t play since Pulstar / Les bootvideos ne jouent plus depuis Pulstar:
@Sesto2k If you wait for Recalbox to fully boot, then connect via ssh and run
/etc/init.d/S06splash startdo you see a boot video then?
Tested this..but no video ;-(
OK, what if we try commenting out the feature that stops the boot video if a gamepad button is pressed?
I edited the file /etc/init.d/S06splash and on line 150 I added a # at the beginning of the line so it reads:
# options+=(--input-conf=/etc/mpv-input.conf --input-gamepad)
I saved the file then typed:
es stop /etc/init.d/S06splash start
The video played and pressing a button didn't stop the video.
What can I say ? I set the write permissions with Putty, then edited the file with the "#" in front of the line with WinSCP and saved it... what happens:
I HAVE MY VIDEOS BACK
Thank you very much Pooadum!!! You are the best !!! ...and I got into programming a bit 
P.S.: I hope the write permissions are automatically deactivated again after the restart....

Cool
Bear in mind that change will be overwritten when you update Recalbox.
P.S.: I hope the write permissions are automatically deactivated again after the restart....
Yes, it will be read-only again after a reboot
Yes perfect... THANK YOU SO MUCH !!!
I think all the searching was worth it because there will certainly be some players who use these controllers and now you know what can go wrong when booting
P.S.: Maybe it would be cool to have a setting within the Recalbox that would allow you to enable or disable the ability to skip the video
@Sesto2k arg yes the feature is pretty cool but if your controller keep sending evens it won't work well 
Cool you managed to fix that
Yes of yourse
I can't tell you why the controllers behave like that either. I did some research on this but didn't find anything really useful. I'm thinking about switching to a different USB encoder anyway (2 player board). But for now I'm happy and it works...both on the RPI4 and on my new Mini PC. As I said, thank you very much for your great help
