Hi..i also using Ac Ryan Mini connect to my LCD samsung by HDMI, then monster fiber optic cable connect to my AVR 140 harman kardon , but when i play the movie with the audio DTS and DD5.1, My AVR just show to Lelf and Right signal that function well but that not signal at my Rear speaker ( I'm tried all the audio mode in my AVR such like Dolby Surround, DTS surrround, DTS NEO:6) ... Simply speaking it just like playing 2.1 speaker is stead of DTS and DD5.1 function. 

Then i check back with the spec of AC ryan Mini it show that:

Stereo
Dolby Digital AC3 5.1 (passthrough & downmix to stereo)
Dolby Digital Plus (passthrough)
DTS (passthrough & downmix to stereo)

1) May I know what the mean "passthrough" ? It is it really work on Dolby Digital AC3 5.1 and DTS?
2) I not really like the sentence "downmix to stereo" even i not so understand this sentence...?

I check my AC ryan that firmwire is show v7.0.21r 2898.... Is it this is the firmwire problem that can not support those Dolby Digital AC3 5.1 and DTS??? If so may I know which firmwire that can support this?

Hope that AC Ryan can give a good respon to this since we buying this to enjoy the Dolby Digital AC3 5.1 and DTS effect....but it seen like we get cheated...Hope to get good respon from which guy that familiar with this.

Thanks.

Is POHD capable of streaming straight from a mac/apple network? Or do i need a NAS to make that work?

What programs did you use to do that?

Or by default sharing the folder will be seen on the POHD?
