I received a video via email and now when I go to actually watch it and tap on it, it says no application can perform this action?????? The filename was saved as My movie.wlmp... I dont know if that has something to do with it or not... Ther Has to be a way!!!
The GS II probably does not support said format. The only app that I know will play most (if not all) formats is the VLC player, sadly I don't it has come out of beta yet. You can also try one of the video converter apps in the market, though I don't know if they support wlmp either. If you can't get any players or converters to work, your last resort would be to export the file onto a laptop/desktop and convert the file into something that is format compatible.
