Miro is re-adding last session's "new" downloads on startup, filenames only. I've been using Miro for about 2 weeks, and my hard drive has filled up (Ok, I've been using it a lot). I bought a new 750 GB HD, and moved the files from E: to F: using Windows Explorer. I think this is the timeframe where everything went south. Now, when I download any new videos from searches or my existing channels, they get added to the new directory list as normal, I watch them, and they get tagged as watched. When I toggle to a channel and back to the new directory, they're gone, as normal (this is a nice organizer). HOWEVER, after all or some of the new videos are watched and removed this way, if I shut down Miro to do something else, then come back later, when I restart Miro, it re-adds all those recently watched videos to the "New" list, but only as filenames, none of the friendly titles used before. This also happens if I DON'T watch the videos. It may be related, but upon starting Miro, every time, I get an error window "Internal Error: Miro has encountered an internal error. You can help us track down this problem and fix it by submitting an error report.", with a crash report button. Also, this seems more related, Miro occasionally gives me another error window describing Miro_MovieData.exe crashing (I can't get Miro to give me the actual error right now for some reason). It seems to do this most often after downloading a video, possibly only when doing so automatically when a channel is updated. I can manually tag these unwanted duplicate entries (still only one file downloaded) as watched and they go away, but still end up in my library. Interestingly, these duplicates do not have the "Share" button in their "Length" column.
