Hello,
Thanks so much for your feedback!
How did you watch the video, via SMB, DLNA, AirScreen or from local storage?
Did you return to the main menu when the video abruptly ended? The playing history may not be remembered if there is a crash.
Besides, would you mind taking a video recording about this problem("Invalid Video Format")?
It would help us better checking this issue if you can give us more information about the video, like the file size, resolution, video format.
In additon, you can send a bug report to contact@skybox.xyz. Also, you can click "Global Setting" (⚙️) and tap "Feedback" (⚠️) to report bugs. Of course, you can submit bug reports at our forum as well. 🙂
Let us know if you have any other questions.
Best regards,
Lucy
