I have a number of movies on my PC in the form of folders containing *.VOB files that originated from DVDs. I see that there are a number of Android apps that are suppose to be able to playback *.VOB files. I tried a number of them after coping a folder containing the movie to my V20 device. But the movie will either display as garbled or black screen. Is there a decent app that actually will playback the *.VOB video files?
