Hmm this is very strange...
This problem never came up on either the UE beta testing or Movie Player beta testing, and i'm not really sure what the cause is. The latest version of the Movie Player (1.2a) *should* be able to play the UE movies without any difficulties.
The only 2 error messages that the code of the Movie Player (same one as the FMV patch UE uses) produces are "Error loading dll" (when the DLL isn't found or loaded properly) or "Error getting decore procedure address" (when the decore procedure isn't found on the DLL). If the error message that appears doesn't look exactly like one of these, the error is being generated somewhere else. Does the error message give any more information? What is your operating system? (98, XP?)
The divx DLL supplied with the player and UE are the same, and to the best of my knowledge, are working fine. Replacing the divx dll with another one isn't likely to help: the player and patch use the decore procedure on the DLL, which is fairly specific to the OpenDivX DLL, as i understand it (most other divx DLLs don't even export this procedure, and expect the programs to use DriverProc, which for the purpose of WCSO would add unnecessary overhead)... I could try statically linking the opendivx library instead of using a DLL: no guarantees it'd work, but if you're willing to try it i'll be glad to send you a version for testing by e-mail.
Do you have other divx dlls on your hard drive? Not that it should matter tho, as windows *should* look on the current directory for the DLL before anywhere else. Can't really think of anything else... but i will look carefully into the matter
Has anyone else been having the same problem btw?
Merry Christmas to all,
