Quartz Builder/Quicktime Thread issue

Hey all,

I'm running into what seems to be some trouble with Quartz Builder. Basically, we have a video capture going onto a billboard and sending the feed to a Syphon server as well to allow users to record their own videos. Everything works fine when run in Quartz Composer, but once I try to run it through QB to package it as an app, the video feed crashes almost immediately.

After turning on error logging, it seems to be a threading issue:

[12:02:42.558] ERROR: Running movie on thread 0x1026bc000 while initialized on thread 0x13b889000 [12:02:42.558] Execution failed at time 71.591 [12:02:42.591] ERROR: Running movie on thread 0x1026bc000 while initialized on thread 0x13b889000 [12:02:42.591] Execution failed at time 71.624 [12:02:42.624] ERROR: Running movie on thread 0x1026bc000 while initialized on thread 0x13b889000 [12:02:42.624] Execution failed at time 71.658

and so on.

We do have a version that seems to work despite compilation, so I guess we're not completely up the creek, but knowing what went wrong and how to fix it would also be great.

Any thoughts would be greatly appreciated :D
