Rip DVD to file, then re-rip for every new device

I have looked, and I have read too much. Brain indigestion.



I have lots of DVDs that I want to sell.

Ordinary (not blueray or 3D or anything fancy) films and TV series like Stargate etc.

I have already ripped them for viewing on my iPad using MacX DVD Ripper Pro.

However I now want to view them on AppleTV on my big screen.

And no doubt one day I'll want a better version to view on a retina iPad.



So do I need to rip the DVD as an iso (perfect copy but huge file) or an mp2 or mp4 - with H264, (perfect copy but smaller file), so I am future proofed when I want to convert for a new device using MacX Video Converter Pro - just as if I still had the DVD?

Quality is important.
