Why does the new 64-bit Vegas Pro 9 not have a preview in Video capture?
Initially, one of the components we rely on for HDV capture preview was not available in a 64-bit version. Rather than delay the 64-bit version or remove the capture feature, we removed the preview during HDV capture. This has been addressed in the Vegas Pro 9.0c update. Please download and install that update. If you continue to see problems, please contact our technical support group so that we can work through it with you.
