37179 Powerpoint to DVD and Flash

I am looking for someone to convert my powerpoint presentation to dvd and flash. The ppt presentation is 35mb zipped and I had two guys try already but the software they are using doesn't help because the voice-over and the slides are out of sync when converted. Also, the trial software I downloaded does the same. I am also looking for a way to reduce the file size without losing the look and sound.
