I tried blu-ray dvd writer with ezq product. I bought internal drive and try to install, but there is no connection for MacPro, so I bring my computer to their place in anaheim, CA. Wow, they even don't know new MacPro inside configuration. And technical support & president trying to another part for installation, but cannot did. Then they gave to me external blu-ray dvd burner with firewire 400 connection. I tried install by myself, but MacPro Pro cannot read their drive. I call their tech support, they say restart MacPro, and turn off ezq externeal blu-ray dvd drive, and after turn on computer, turn on blu-ray drive and then wait for 5~6 second and connect firewire 400. Yes, I can read their drive. They said firewire have a problem right that. But real problem is started. I bought Toaster 10 Pro from Roxio.com. When I use this software with ezq drive, the program freeze many times. I notice whenever eject blu-ray media disk, the program going freeze. Then I have to restart again. So I bought another External Blu-ray Dvd writer from Lacie. The Lacie drive easy to read by MacPro, and never have problem like ezq drive. I've tried a 3 whole day, but the program is never freeze with Lacie. I think ezq has technical problem. I came back to ezq office and I ask to refund. And they treat me with bad banner they told 'we can refund at next week' How come, I paid by credit card. They can refund right away. Real problem is after refund process I singed refund bill. After come back my home, I've shock. They charged again without my authorization. I am so upset. They have bad technology and also bad business manner. So I decide that I gonna share this information with mac user. Please every mac user be careful their products. And I hope the Apple company make blu-ray dvd writer for many mac video professionals.
