I don't know about .grp files, but my curve records video in .3gp extension and it plays perfectly well through a free player called VLC media player, google it and have your F&F download it too, that way you won't have to convert anything, just email it from your phone
I think you tube will allow a .3gp to be uploaded to their site, but I don't know for certain...
