So funny you should say that. I had our Thai house guest translate it for me!
When I was in Bangkok I asked the distributor how much it would cost to come out with a subtitled version and he said I would have to order at least a 1000 DVD's to make it worth his while. I doubt there is that much interest in the English speaking world...?
I have the original video on one DVD, and took notes when my friend translated it for me. In the same series, I also have a DVD about Asian arowana, one about Flower Horn and other hybrids, another on Amazonian fish and one other on Discus. All of them are in Thai. PM me if interested.
