Don't mix Taiyo Yuden up with the Hyundai crap
Hyundai is bad Taiyo Yuden is good. Hyundai discs are bad everywhere. I never heard of a place claiming they sell genuine TY actually sell fake. That would be fraud and very shortsighted. dvdshoponline wouldn't still be online if they sold fake Taiyo Yuden. They sell Hyundai with fake TY id but that doesn't make the discs TY and i don't think any seller would be close to claim Hyundai is close to TY quality.
Hyundai = crap
Taiyo Yuden = ok
I could possibly say it in many more words but will leave it to others
