I agree with you ctebo about using ifos/vobs for all the main DVD players out there. But I was talking specifically about DVD Ripping for myHTPC as per the thread. A large majority of people who use myHTPC use simpleDVD because of it's seemless integration as the native DVD player.
There are probably advantages and dis-advantages to both types of rips. Depends on the person I guess.
Truth be told I find both techniques about the same overall. I just decided to go ISO mainly because it's easier to maintain. I also figured I could pretty easily convert the ISOs over to IFO/VOB format pretty quickly if needed.
Regardless, getting back to the thread, the better way will be however Beyond Media handles ripped DVDs!
