Richard and Josh,
Thanx for your patience and guidance.

"what you have here is parameters that interact.

I cant repeat what you see-

but in this example you dont need to change the playback speed in any cue.
'Inframe' playmode does not play. Leave playback speed at 100%

Also suggest you check the commands you think you are sending to catalyst - using the catalyst GUI.

For example when you say frame 1 - your user interface is using an offset from 1 - my user interface uses an ofset from 0."

Sorry about the reference to Frame 1 instead of Frame 0 that is just my newbieness showing. I used the wrong terminology.

Which parameters are interacting in this sequence?
Play Mode and InFrame - I expect that
Play Mode and Playback Speed - I expect that too
InFrame and Playback Speed - probably not, right?

In the sequence described, I change the playback speed because the designer wanted to see the movie start slower and then play at speed, essentially giving the movie a slow bottom.

Given that some parameters interact, then how do they interact? For example If I know that I need to select Playback Speed before Play Mode then I can construct my cues to get my desired result.
Thanks again.
Michael
