I haven't had to play a DVD since VB6 but when I try to play the DVD in VB.NET 2005 I get a "Managed Code (MDA)" error saying something like "Loader Locked". Here is the code that I used in VB6 and is the same code I tried to use in VB.NET 2005.
"DVD" is the name of the MsWebDVD control
DVD.DVDDirectory = "D:\VIDEO_TS"
Any ideas on how to play a DVD with the new VB 2005 environment?
