I've recently upgraded from 14 Ultra to 15 Ultra and now when I play DVDs, I'm having a few issues.

The first issue is that if Video Enhancement is on at all, when starting a DVD for the first time, it displays as though all settings are on even if though only HD & Noise Reduction are set. Clicking the blue eye icon (Video Enhancements) causes the settings to quickly apply correctly when the dialog opens. Once closed, the settings will remain correct until the application is restarted and then will be incorrect on the first DVD playback until the icon is clicked again.

Another issue I'm seeing with DVD playback is that I have 2 monitors and if I have the window in the second monitor, DVD's with 16x9 playback at full screen appear to be using the other monitors dimensions and stretch the image incorrectly. Clicking the off the full screen icon fixes the incorrect scaling, but then it shows the top and bottom bars controls all the time.

These issues don't appear when playing blu-ray disks. Also, neither issue was in 14 ( or 13,12,11, ...)
