Only 8,367 people asked that before. Read the limitations of the trial version.
For the reading impaired:
*The trial version of Adobe Premiere Pro CS5 does not include some features that depend on software licensed from parties other than Adobe. For example, some codecs for encoding MPEG formats are available only with the full version of this product.

it would be nice if the trial version had a pop up box that said the files you are trying to use are NOT supported by the trial version.
Even if people do read the limits most do not understand what it means.
I guess they think that their not using MPEG but not understanding that the files there are using is in the family and NOT supported.
Some day ADOBE will figure out how to get past that limit.
Till then, Good Day: GLenn
