I have a commercial, locally produced DVD about business practices that will not play on my computer ... the green light comes on but none of the usual disk spinning/whirring sounds. Also, viewing the drive icon shows no disk/file/s. The drive works for every other videao, movie, sound disk I throw at it.
Now, the DVD in question WILL play when I connect and use an external, USB DVD drive, AND it will play on the DVD player connected to the TV.
I've checked the usual suspects like codecs, autoplay settings, file types etc etc.
Any ideas folks?
R.
