DVD Burning failing?

We have been having a few issues with our DVD burning functionality, particularly when the video being burned is longer than 2 hours and a dual layer disc is being used. However, a rather odd fix has been found that we are currently trying to get to the bottom of. Once we find the time and resources we shall be giving our DVD burner a complete overhaul. But for now the fix is as follows.

1) Don’t open ConverterLite
2) Locate the folder with the file you wish to burn
3) Right click on the file
4) Select “Convert with ConverterLite”
