According to the details of this item provided at sendit.com, the DVDs have English subtitles for the hard of hearing. However, I cannot confirm whether this information is correct not having bought the set myself.
Hello all, I bought this setbox 10season complete "Friends". I received it today and apparently it does not have spanish subtitles. I need them as I am spanish and my family cannot speak english. Before open it I would like to know surely if it does or does not have. Otherwise I will try a refund. Please, can you help me? Thank you very much and regards. Friends: Complete Season 1-10 (30 Disc Box Set) [DVD]
