The wine 5.5 announcement says that Oddworld: Munch’s Oddysee should have working movie cinematics in wmv format now. But the Lutris Build 5.5 can’t play them. Is that a bug in this release or something is missing?
It could be a bug. This stuff is still very new for Wine and heavily being worked on so it could just be not working in some cases still.
Many games will probably still have problems playing (if they even can at the time of 5.5) Windows media. In some more time it should be improved.
