Ok, after Perry sorted out the playing a vid issue here :https://community.clickteam.com/threads/101488-Clarification-on-Video-players-please
I ran in to another problem which MAY be related to the video...or not?
I noticed that when on frame 1 I started a sample (Chn1 uninterruptible) and then after jumping about from frame to frame I went to the frame holding the video, and the sample just stopped dead.
I have checked that the sample will play over frames, and it only stops when it gets to the video frame.
Im using the AVI Object to play the video.
Is this a known bug or should I be doing something else with the sample to let it play on the video frame?
