I must admit...you have a good forum going here. Very useful and full of info.
I'm considering getting a Meizu. After looking around EVERYWHERE, I am still confused - is there a difference between what is sold as a MEIZU M6 and a Dane DA-M4-04-MZ?

I've read the thread on how to interpret serial numbers, but obviously I have not bought one yet, so I can't analyze anything.
For example, on a major electronic retailer website, they are selling essentially two different Meizu 4GB players - one is listed as an M6 and the other is Dane DA-M4-04-MZ. There is a 2X difference in price.
Are these the same player?
One description says the M6 plays Xvid format videos, the Dane DA-M4-04-MZ2 plays AVI. One us listed as playing OGG, the other isn't.
Can they both be upgrade with the exact same firmware? If so, is it safe to assume if upgrading to the latest Meizu firmware will get me the exact same specs (audio, video, etc...)?
I'm really confused....any help is appreciated.
