It depends upon which module that instruction is in. Any process viewer can tell us. I use ProcWin v1.6 (my build) or TaskInfo2000 v2.1. Dependency Walker in profiling mode will also reveal module load addresses.
Or try a different codec pack. If it works, great. If the error is different, it's probably the codec; keep trying. If the error is the same, it could be WMP7's AVI file parser or splitter; not good, the file is invalid or otherwise incompatible.
