There are some reps from Corel that do participate. However they are volunteering their time here, it is not as a part of their normal support duties. This web board is, as it's name specifies, a User to User web board. It is staffed by, and for all users of Corel's digital media products, to help each other. So the lack of response by any Corel representatives, is not a reflection of their support.
FWIW, I'm using Q.T. version 7.6.9(1680.9) on my WinXP machine, which is a single-core AMD, and do not have the crashing when creating 3-D videos. So either I'm extremely lucky, an exception to the rule, or this crash is not due to a specific version of Q.T.
