I am using build 14.0.155 with Windows 7 64 bit.
With GraphEdit I can use the ffdshow video decoder, Nvidia video decoder, Microsoft DTV-DVD video decoder, or the MPC-MPEG 2 video decoder.
With MC, I can't even select ffdshow video decoder. It isn't even available. If I choose Playback Method: JRiver Video Engine (using DirectShow filters) and select codecs, sometimes playback works and sometimes I just get the message "DVD Playback Error."
If is set Playback Method to be set to Automatic and audio decoder, video decoder, and video render all set to Automatic it will play using the Microsoft DTV-DVD video decoder and ffdshow audio decoder. If I leave Playback Method to Automatic and change the audio or video decoder I get the message "DVD Playback Error." It is like the Automatic setting isn't working right.
I even tried installing the complete CCCP and still had the same problems.
Something strange seems to be going. I have had this happen on two different computers with Windows 7 and 14.0.155.
