OK, all you guys out there using Windows 7, I have a weird issue that occurs with video DVDs. The normal ones like you buy at the store that have a movie on them. Sometimes I will put one in my DVD drive and Windows Media Player will autolaunch and play the movie. This is what I would call "normal behavior" Other times, for no apparent reason, the disc will do its loading thing but nothing else happens. If I look at it in Explorer, I notice that there's no volume label, it just shows up as "CD Drive (D: ) 0 bytes free of x.xx GB UDF" and if I then "open" it I see the normal AUDIO_TS and VIDEO_TS folders, plus "Files Ready to Be Written to the Disc (1)" containing desktop.ini. No amount of coaxing will get the thing to play, in fact Media Player says the drive has no disc. This is not a writeable disc. Why is it doing this?
