I'm about to buy a TS-212 with the intention of using it to stream our DVD collection to ipad and Apple TV.
After reading some posts on this forum, I am right that if I wanted to keep the DVD structure (discs of TV programs that need a menu to navigate) I would need to convert them to ISO files?
That is one way of doing it. Huge waste of Diskspace if you ask me. I personally rip individual episodes to individual files so that I can use the menuing system of my network media player to browse the "Series", "Season", and then "Episode".
I'm neither an Ipad nor a Apple TV user tho', so perhaps you'll get better advice from another Ipad/Apple TV user.
