Video encoding is a viper pit of issues. But rather than ask 100 questions about the tablet which has to decode whatever you choose, why not go get VLC Player on the tablet which will play just about anything.
That's what I did.
My son and daughter took a long trip and took a whole DVD full of video.
They had all their video put on a DVD+ disk while on their trip.
They ask me if I could take that DVD and transfer it to a Micro SD card so their daughter who only has a tablet can watch them.
I have Googled on how to do that and get conflicting ways to do it.
From what I can see is, I have to make their DVD either a MP4 or MKV file then put a program on her tablet to play that file, Is that correct?
Have never done anything like this before so am pretty much in the dark.
Thanks for any help.
