I ordered Kurt Osiander's videos. It was a 4 part DVD. Disc 1 does not work at all. It looks like they were burned on someone's home computer with a homemade label maker. I called the number on the website and a message says it hasn't been set up yet, so no contact. I sent and email and so far I've gotten no response from the company. I spent $80 bucks on something that doesn't work and can't get anyone on the phone to exchange or replace the disc. Come on guys! We got to do better than this!
