What file formats are compatible with a Toshiba TV?

I have a Toshiba 32BV500V.
There’s a USB slot where I can put in a USB memory stick.
I managed to watch a film from the USB stick on the TV earlier, so I know films work.
However, I tried to watch something different just now, and it says it’s not a compatible file format. I don’t understand this because it’s the same format as the film I watched previously.
Please help me.

The manual doesn’t say anything about this.

Thanks in advance.
