This has only been asked a 1000 times if not more and never is the FAQ section consulted.
There is no MPEG capability in the trial.
Get the full version for that.
Thanks for your response. I consulted the places I could, from the help files to external forums to this one. I apologize for not knowing about the faq that you are talking about. Next time rather than ostracizing someone for asking a "stupid" question, why not provide a link so that they can learn how to find their own answers.
I apologize for not seeing that you are new here and that my tone was not welcoming. It has however been told over and over again and I overlooked that it was your first post here. Sorry. Nevertheless, my message I hope was clear, due to licensing issues, there is no MPEG support in the trial version. Your only option is to get the full version.
I have suggested to Adobe on multiple occasions to make it more obvious when downloading the trial that it is crippled. But, they dont seem to think its a good idea. It causes lots of undue confusion.
