It seems that this way I can solve the problem, thanks for your answer
It seems that the file explorer does not show the videos, it is something that must be solved.
But SPPB 4 constantly has unexplained problems that lead to continuous delays in the development of projects.
This did not happen with SPPB 3x, I was very happy with the product until version 4 and it is something general in the Forum
So I encourage developers to listen to the forums and work hard checking that everything works before releasing versions that cause a lot of problems.
They should open a specific channel to report operating problems and that these are resolved in future updates.
Thank you very much again Paul
