The trial version is fully featured (with a few minor exceptions). It just times out after 30 days. ppro had a few avc-intra codecs for export, btu they're not needed to import or playback your AVCHD footage. If you are unable to import or plyaback & edit such footage, then you are encountering some otheer problem. To avoid possible user error, its a good idea to use the media browser to find and import media such as AVCHD video.
