AW: Trouble playing videos with MS DirectShow LC 8

choosing a video file via ask dialog and setting the filename of the player object to it sets an absolute path and that works on my machine fine.

Thank you for that hint

Tiemo

Make sure your file references to the movie are relative and not absolute. I’ve made that mistake once or twice.
