So recently I've been having yet another issue with this software. For some reason the audio waveforms of certain files are displayed incorrectly, different from what the actual sound is. Only if I prepare the files do they sync up correctly, but I do not like to prepare the files because it lowers the quality in the preview. Do you have any ideas as to what could be causing this? First of all, don't ask me for the latest version of Movie Maker. You haven't updated it in three years. Of course I have the latest version. Second, don't ask me to check my codecs. I can assure you that they are all updated and working properly. Don't ask me to check my audio drivers either. I just recently updated them. And no, I will not roll back to the previous audio drivers because they were starting to give problems. Thanks in advance.
