Dear ucbthaf,

We apologize for the problems you are having with the Videoplayer. What version of LWDAQ are you using? What operating system?

The Videoplayer in LWDAQ 10.6.1 is broken on MacOS and Linux. We are working on fixing the Videoplayer right now, and hope to release LWDAQ 10.6.3 later today.

Best Wishes, Kevan

We believe all problems with video display are fixed in LWDAQ 10.6.2, available on GitHub for "git pull" and as a ZIP archive on our software download page.

Please try the new version and let me know how it goes. Kevan
