Although I don't know exactly what you are trying to accomplish, I would think you would just want to overload the function with different parameters. For Example: void MyFunction(strHeader tStruct) { // Do Somehting } void MyFunction(dataStruct tStruct) { // Do Somehting } Dustin

Thank you very much for the advice. You're right, I do not need most of the features in VMR and I can work with any format I want as I am authoring the videos. I will give it a go, although there may be more questions coming.:) Thanks for always being so helpful Mark, Dustin

Thanks for the advice.
