I've downloaded some videos from YouTube with Conceiva. These videos were at least 5 hours long and 720p or better. However, it turned out that only about half of the file was downloaded. At first, I thought maybe the player was the problem. But then, while downloading a video DownloadStudio was estimating to need another 40 minutes, it suddenly said it was down. That left me rather confused. Sure enough, the file wasn't completely downloaded. While I said only "half" downloaded, I don't know the exact ratio or how consistent it was. I do know it did later succeed in downloading each video...but I had to delete the existing job (and file) and recreate the job.

What's going on? Any ideas? Could I be experiencing a bug?
