thx,

Bogie:

Thanks for that info. I will relay it as well.

I managed to replicate the problem, establish a pattern and come up with a workaround. Hopefully, this will give enough hint to the mighty engineering team in Burlington to fix it. So here it goes:

-if project is launched with no BOB attached, system works fine

-if project is launched with MojoDX attached in green-green 8/10bit modes, system will not hang

-if project is launched with MojoDX attached in yellow-yellow or yellow-green modes, system will consistently hang after 1 second of playback

-later today I will try to test with a NitrisDX box as well

-WORKAROUND: right after the project launch, change the video quality button (doesn't matter if you go back to a yellow mode). This will avoid the crash and you can enjoy a fully functional session. If launching in green-green, you don't need the workaround(see above)

-project format, framerate and media type seem irrelevant to the issue

Relayed your info and workaround to engineering.

I've got the time to test with the NitrisDX box as well.

Things are similar, with the exception that once hung, the Nitris system will require a full shutdown of both CPU and BOB in order to come back to sense and be able to playback anything(again, only in green-green modes, yellow is not good)

Same problem here with Blackmagic Intensity Pro:

If I hit Play MC6 freezes after 2 seconds.

My workaround:
- Start MC6
- Open project
- Capture a clip
- Close Capture

Now it works to me. 

Larry,

I ran the HW test on the Nitris DX -- the firmware update is there and all tests passed.

Hang on video playback ramains.  I noticed that audio files play fine, but no go on video playback with Nitris DX connected.

Thanks, Vince. Information relayed.

Yes that workaround works, but what happens if you change the  Workspace from record to source/record editing or to effects editing and try to play.

At my system the program will crash

Same problem but I am using Matrox Mini.

Workaround reset Video Quality from Green to Yellow/Green.

I was working on a project and it just started to happen. This was after many days days with no problem.

MC6 download upgrade from MC5

Sometimes, after just have been started up, I can see a hang and freeze if I begin with playing the Sequense the first thing that I do.

If I, however, starts with playing the source viewer for a couple of seconds, all runs well after that.

Mostly I don´t see any hangs at all however.

Sorry for the bump but I am having exactly the same problem. Found a couple of threads describing this issue but they seem to stop without any issue.

This is happening for me on my z400 DX Nitris MC 6.0.1 machines.

I am about to log a support case but was hoping someone had come up with an answer?

I've pinged Marianna.

Marianna has said they expect this to be fixed in the next update.

Gents,

I had the same problem with video playback freezing on NitrixDX.  Enabling Hyperthreading in the system bios fixed the issue. Now if I could get Pan & Zoom to work smoothly…
