OK. Can you confirm the error log below is when you start playing a dvd, or is happening all the time now? Also confirm, did DVD's used to work for you. ie is this something new? Here's possible errors I found in your config. I noticed in the config, an MPEG 2 Video decoder is not specified for DVD's In addion you have the use FFDSHOW setting turned on And you have VMR 9 turned off. Look at those and post back. Thanks. Tom.
