Just FYI, your image even exceeds the DVD-9 (aka dual layer disc) size, so the only way to burn it without re-authoring/modifying would be to use a Blu-ray media (since you have a Blu-ray drive in your system anyway). If you still want to go with the compression method, then you should try some re-authoring software, e.g. CloneDVD2. However, there is a plenty of similar apps available, google for them, see what fits your needs best.
