Hi Matthew, We're here. Unfortunately I don't have Windows and would have a hard time trying to reproduce this problem for you. (It works fine for me with gcc on Linux; I recognize that's not very helpful to know.)
Are you able to compile the "mpeg2dec" program that ships with libmpeg2? Does it also bomb out like this? I didn't understand your remark about "I assume the source files for the .obj files in vc++ cannot be built with VC++". Are you saying you're not compiling libmpeg2 from the source code and just using somebody else's build? Sorry for the confusion.
