Hi Steve, thank you for taking the time to write to me. The option is checked by default in Preferences, as is the one about audio ports.
After a couple of uninstall / re-installs, the problem has become arbitrary.
Now most times I can export audio clips normally. Sometimes the error does appear, but restarting Vegas allows me to export the same clip normally.
Other parameters: at least 1TB free on all Vegas- and content-related drives; 12 GB RAM; raw files – avi/mp3 or wmv/wma – b/w 1 – 2 GB each, only 2 – 5 processed at a time.
I’m not able to replicate the error a 100% anymore and with this vague input I can’t ask you to expend more time on this. Once again, thank you very much for reverting.
