Desktop Video 9.6.1 problems

I, too was having memory issues with Intensity Pro/9.5.3 and PP CS6 (Win7)

However, today I have had to remove 9.6.1:

1. Timeline will start to play.
2. About 20 seconds in, vision will freeze whilst audio continues
3. Playhead jumps to start of timeline and appears to be playing - however the audio continues to play without interruption.
4. If I stop/start playback, it will resume from new playhead position until the cycle repeats itself.

This was not an issue before 9.6.1

Native XDCAM EX edit with MPE/Quadro FX3800 and 24GB ram and Raid0 drives.

Disabling Intensity Pro as default playback device resolves the issue.

6.5.2 now reinstalled and freezing/memory issue have vanished - although I'd forgotten the age it takes to send the initial output signal to the external monitor!!

I should have said that this was 1080p25. I haven't tried any other format.
