Crashes - seemingly related to video

[dscid]

I just installed the latest demo, and have been trying to set up a template. All was well- I set up all of the essentials. I decided to import a video, and it became unstable. I wanted to continue pushing forward with the actual template, so I ignored the problem. Now that I've finished the setup, I can't ignore it any longer

The video doesn't seem to cause the crash. Rather, it crashes consistently after extracting the audio to a track.

Any advice/ideas?

I'm not sure about the formats for Windows visual media, but two things to try.

1) Re-export the video to create a new, fresh video file.

2) Re-export the video and reduce the size (resolution).

This may have helped. I was able to watch a shorter animated episode for several minutes. I stopped the video, tried to access the mixer and boom-crash.

So this crash was different in that I tried to open another window (with video stopped, but audio extracted). I tried to open the mixer because after clicking on the Sequence tab, I received an error for the first time, but no crash.

Also, the manual says that any video file that I open with Windows Media Player should be able to be opened in DP9. But .MKV is not showing up as a valid file when I browse for a video and is invalid if I 'Show All Files' and try to open.

I know many people are getting along with DP9/Windows/VEP, so what gives? It can't be a bad plugin, because I have not loaded any plugs besides VEP at this point.

Trashed Prefs didn't help. Crash occurred in Safe-DP9 mode. Is support offered for 'demo users'?
