In a nutshell, when I add more than one audio clip to the timeline the second clip is near impossible to get in sync or to work properly... Video will freeze at the point second audio file is to play, audio is delayed or the first audio clip gets altered. In some cases it can be resolved with much time spent tweaking the audio files length and position on the the timeline but usually I give up before it's sorted out as I've spent literally hours with dismal results and no resolve.

Just as a test I rendered a project leaving out the second audio clip then creating a new project to which I inserted the rendered file, added the second audio clip and I am faced with the same results.

Have the latest version of PD9U (9.0.0.2504) with all patches applied and even performed a complete reinstall a short while back. The type of audio files have not made a difference and even SmartSound causes the same problems... Video clips are mosly of the SD (4:3) variety at the moment but have had similar results with HD content.

Haven't created many projects w/PD9U but I sort of remember the few vids I created before applying the latest patch were not an issue but not 100% sure, anyone else having this problem in a similar fashion?
