The new units have a firmware version which is later than what we all use and it stinks. We have been reflashing with the earlier version. It looks to me that the quality is been lost out of these things.I notice the one on the left has "HDMI" and the Dolby Digital marks printed on it. Along with USB 2.0 indicated.
The one on the right just Digital and USB. No HDMI or Dolby Digital.
Think there's a licensing requirement for HDMI and Dolby Digital, possibly USB 2.0 also. [Smells like a clone.]
What's the firmware version indicted?
