So, I've been trying to move away from the Indeo Codec, and converted all the AVIs to the H264 Codec (in both MP4 and AVI containers). I've tried Hex-editing the Outpost2.exe and OP2Shell.dll to replace references from AVI to MP4 (Didn't work), and I've tried using the re-encoded AVIs, which also refused to be utilized by the game.
At this point, I'm at a loss. Any suggestions here? I'm not exactly a coder, but it'd be nice to have the AVIs in a format that will scale better in the future with Indeo's codec becoming problematic in recent versions of Windows (64-bit Windows 7 in particular).
