PS2 DVD Player Cannot Fast-Forward or Rewind — Only Chapter Skip

You can't. The PS2's DVD player does not support fast-forward or rewind during playback. It's a basic DVD-video implementation with only play, pause, stop, chapter skip, and menu navigation.

Workarounds

• Chapter Skip: Use L1/R1 or directional buttons to jump chapters (if disc authored with chapters).
• External Player: Rip the DVD to a PC/USB and play in VLC, MPV, or any media player with speed controls.
• Streaming/Modern Device: Watch the same film on a smart TV, console (PS4/5, Xbox), or stick (Fire TV, Roku) with full playback control.

The PS2 is a gaming console first; its DVD playback is bare-bones by design.
