Hello...for a certain reason, the Media center plays the videos as files (No access to the DVD menu) just a list of chapters that are played individually. And then I Installed Google Music Play and Player pro and I can't access the root directories to scan my Media....is there any way around that?
What format is the DVD image? If all else fails install Kodi and use that for DVDs.
Google Play can't find your media because it is set up to only scan the /sdcard directory. It's like this because it's designed for phones (and perhaps because Google doesn't want to support local media playback in favour of it's own download/streaming service) and there is no way to change it.
On the Q5/Q10/M3 local storage is at /storage/emulated/0, sdcard at /mnt/mmc, SATA at /mnt/sda/sda1 and USB storage at /mnt/sda/sda2 etc.
All the other music player apps I've tested either scan the whole file system or allow you to specify directories. Some worth trying:
VLC for Android Beta
doubleTwist
Shuttle
Poweramp Music Player (free trial)
AIMP
