This is a quick update if anyone is following the discussion as I've had time to do some more research on the issue.
It only affects Vegas 11 and only when installed on different language versions of Windows. Vegas 8 is English only. Vegas 9 and 10 use the English name for the "Sony Solid Color" plugin, even if another language is selected during installation. Vegas 11 uses the foreign language name for the plugin, even if the English version is installed. The names of the colors do change as expected with the language selected during the installation of Vegas.
I did have a fix in place and was testing the changes when I discovered how complicated it all is, so I'm back to the drawing board trying to sort it out.
I haven't seen these options in DVD Architect so I'm not sure why they affect the burn process but I'll investigate further as soon as I've fixed the foreign language issues.
I had to untick the "XP theme" option and tick the "skip drive database" one to have it working properly
There is also an error during installation of TandemVids on a foreign language version of Windows, which is generated when attempting to set the permissions of the Swoopware data folder. I've fixed this issue for the next release but a workaround is to set the permissions manually to full control for all users. The location of the hidden folder on English machines is "C:\Program Data\Swoopware" but the name of the program data folder changes according to the base language of Windows.
