Im sure I have ever asked why this problem shows on my computer. But until i upgrade to the newest version of smplayer, I found that nothing fixed with my problem. I use mpv as my default in smplayer.
my problem is on all animes with chapters inside. when I press button that can make me jump to the next chapter and I'm still playing in the middle of chapter two(assumed that anime has 3 chapters), the slider goes to the first chapter and anime start from that chapter. It runs fine in mpv when I try to open video itself and pressing button not make slider go to first when I play in the middle of second chapter
