I know ratDVD can take a very long time to process depending on your PC spec and the settings you chose. Please post PC spec and encode settings
For me impossible to make a ratDVD, i've the windows send error at 10% I tried in with many quality, wmp 10 is installed , i've a DVD player installed I don't understand
Are you sure that your system have at least 300 MB of free memory? RatDVD encoding uses a lot of RAM.
perhaps your problem comes from copyright! I had the same problem. you should make an iso of the DVD with DVDshrink wich throw away the protections, and then simulate a drive with the iso using Daemon Tools. bye
