Welcome into the WW Forum, AndyG. May your time in the Gael Serran find you with sword, spear, and staff that are more than a match for your enemies.
As for your question, there are a couple of things to do.
- The virtualdub fix. Expands all the AVI files so they will work properly.
- Run in win95/98-compatible mode. Check the properties on your WW shortcut link.
- DirectX version and drivers. Recent is better...
- Stop in at the Boogre Bar for refreshments and to let us know how it's going.
- Check the soon-to-be-updated Techie Help Desk thread for specifics and details on all these things. I'll make sure it's on the first page, if it has slipped off.
