I presume you are using Power Director 6? I spent the money a few months ago to upgrade from version 4.xx after the attractive function to create my own templates was touted as a feature, only to discover that I cannot "save as" normally by defining a file path in Windows from Power Director OR "open" a user defined template in Power Producer v3. Very disappointing. So now of course in order to get what I really want, I will have to spend more money to buy the upgrade for Power Producer which was not available when I purchased the upgrade for Director. The answer to your question as far as I know (I'm sure you've already figured it out, but maybe by breathing some new life into this post something good will come of it) is NO.. you cannot put separate "movies" onto one DVD from Power Director. That can only be done in Power Producer with the "Import -- Video Files" selection on the Content (DVD) Screen. I hate that I have wasted so much time and money on a simple task. I didn't want to have to go w/ another company, but I think that is what I may end up being forced to do. When I first purchased Power Director, the Produce command opened up Power Producer. Now the two programs are almost completely independent of one another.
If anyone knows differently, please advise.
