Multiple instances of the same video texture material playing at the same time.

Hi, I am a newbie. I have mapped a video onto a plane object in UE 5.3.1 and I am wanting to play 75 instances of the same video media texture simultaneously on the same level. I can get to 45 but If I try to add more, none of the instances play and the Media Texture Resource stops working. Is there a way to allocate more resources to the playback of the video textures? I have 64GB of RAM and NVIDIA RTX 4060. The CPU RAM use is about 14GB.
