as the previous poster noted i too was concerned about the limited nature of the demo, but after email contact with the courteous and knowledgeable developer mr. serbian i took a chance and bought the app. i am truly impressed, it is an outstanding addition to my video tool kit. it has taken every type of conversion i have thrown at it and produced excellent results. the encoding process is at least 3 times faster than ivcd and approximates the length of your input file. for example a 65 min .mov project took 75 min to convert to mpeg2 and a few more minutes to burn. quality was almost at the level of a store bought dvd. very little pixelation or blocky stuttering. audio/video mix very smooth. extremely easy for the newbie to mac and video conversion to use. one-click dvd works flawlessly. countless options for the more fluent videophile to explore. customer support the best i have encountered on the web. help is just an email and seemingly a few minutes away. put your worries to rest on the limited demo and try the full package. you will be happy you did. 5 STARS
