I've been keeping an eye out for My Neighbor Totoro, I haven't found a copy yet though I've watched the film already. I actually want to find the original FOX english dub as it's different from the Disney dub that's currently available. The FOX dub was mostly released on VHS, though it was also released on DVD for a brief period.
I didn't get the manual with this Windows 95 disc so I don't have a product key. From what I've found so far, it seems it just uses an algorithm to verify a valid product key so I just would need to use any one that's listed online. At least it's not a useless disc, the only reason I bought it was because it has USB support.
I plan to get all those films eventually, I just don't want to spend that much on DVDs as it'll get too expensive. I barely want to get DVDs for $5, I bought plenty of VHS tapes for various movies back when they were over $20 each yet are barely worth $3 now. I might get the Ponyo gift set as I have a gift card for a local store that deals with DVDs and music, but I'm not sure yet. Was your copy of Totoro the Disney dub or the FOX dub?
I'm pretty sure you meant The Cat Returns . I haven't seen that yet but I have seen Whisper of the Heart which is where the main character originated from.
