I guess we could try to overcome it by previewing these files before completing the dwnlds. I mean if launching them won't allow us to play them, then use the drag & drop feature that's been added to LW. ie: D & D to another app such as audio/video player (or I wonder if you could use GSpot the same way.) Or use GSpot on the incomplete file in the incomplete folder. I've never used GSpot so I don't know whether it can be used on incomplete files, etc. See Drag & Drop ability
