Okay, it finally finished. When it was done, just clicked the launch button and it played fine in real player. It also plays fine in windows media. I checked out the real player website and according to them *sometimes an error message will occur when trying to open an incomplete file* While it works sometimes and not others is still a mystery to me, but considering the number of people who were sharing this movie I didn't give up and kill the download. Still being an "noob" I've gotten a few sneaky ads and just delete them. Same with downloads that have a corrupted file message. So my advice is if it won't preview, BUT a fair number of people are sharing it, AND the file size is huge, then finishing the download is probably going to be a safe bet. Hope this helps some people out there.
