*Adobe Encore® CS4 software is not available as a trial. Encore CS4 will be installed as part of the trial DVD set for Creative Suite 4 Production Premium and Master Collection but will not be available for use until you purchase. The trial versions of Adobe After Effects® CS4, Flash CS4 Professional, Adobe Premiere® Pro CS4, and Soundbooth® CS4 software do 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 these products. HDV, XDCAM, and AVCHD formats and sequence presets are not supported in the trial for both Mac OS and Windows®. Adobe Media Encoder export does not include MPEG-4, MPEG-2, MPEG-2 DVD, or MPEG-2 Blu-ray as export formats in the trial. The file importer does not recognize file types that are not included in trial mode (such as MPEG and XDCAM files). HDV is not included as a capture format in the Mac OS version of the trial.
Found here http://www.adobe.com/products/aftereffects/faq/. Nothing you can change. You need to buy the program to use MPEG-related features. Until then the file must be converted externally.
