I repeatedly received the following error message after installing Build 157. "The provided stream is too large for the current inserted media." After many attempts I uninstalled and reloaded Vegas Studio 11 without installing Build 157 for DVDA on my Vista computer. Now it burns correctly. Hope Sony will correct this bug.
I have the same problem. The file was only 4.1 gb. I even tried to burn a DVD prepared and burned successfully with 4.5 but it failed with 5.0 Build 157. I then burned the DVD with another software without any issue.
