Streaming and Capturing Choppy since installing 7.2

Since we installed 7.2, we are not able to stream using Wirecast 6. As soon as we choose an audio input, the video immediatley becomes choppy and it is not acceptable to stream or record. This only happens with Wirecast. If I use the Matrox H264 capture I have no issues.

Hi,

Can you confirm Telestream Wirecast version?
What is the operating system version?

With latest Wirecast 6.0.4, you will need to use Mtx.utils 7.7.2.2018 drivers. See this posting: http://forum.matrox.com/mxo/viewtopic.php?t=13917

When installing the Mtx.utils, please follow the steps below:
- uninstall the current MXO2 drivers
- download and right-click the Mtx.utils exe file and select Properties. Under the General tab, click unblock (at the bottom) if it is seen.
- Make sure the UAC option is turned off (set to Never Notify in Windows 7 settings) before running the MXO2 setup * may need to reboot
To disable UAC option or set it to Never Notify in Windows 7, please follow this link: http://support.microsoft.com/kb/975787
- Run Mtx.utils setup and then make sure a full reboot and power cycle is performed (after install is complete, shutdown PC, disconnect MXO2 power for several seconds, reconnect power of MXO2 and then power up the PC)
- re-enable UAC option if needed

Please let us know your results.

Thanks for responding.

Wirecast Verson: 6.0.5
OS: Windows 7 64bit

Followed the instructions, but still have the same issues.

Uninstalled everything, Wirecast and Matrox. Installed Matrox 7.7.2.2018, restarted. Finished installing.

Then installed Wirecast 6.0.5.

Still same issue.

You will need to install Matrox last in the chain. Therefore, first install Wirecast and updates, then install Matrox drivers.

Since you have Wirecast installed already, can you uninstall and reinstall Matrox 7.7.2 drivers?

If you still encounter issues, try resetting Wirecast Preferences by following the Telestream link below: http://telestream.force.com/kb/articles/Knowledge_Article/Wirecast-Reset-Preferences
