I wasen´t thinking of lessons, I was thinking if I could buy episodes digitally, like iTunes, DVD´s or Blu-Rays, I own Hellsing, Death Note and Elfen Lied but I don´t recall ever seening an option for English subs and Romaji subs on a DVD. I wondered if it existed at all, and if it does where I might get episodes like that. I checked Amazon.co.uk they don´t mention anything about Romaji subs. Being who I am of course I´ve let friends borrow all 3 shows and for quite a while now, I should perhaps collect them all again soon from them, but just as long as I know where they are I´m not much in a hurry.
Just an explaination as to why I had to go to amazon to figure out subtitles on my DVDs.
