Bloody AAC 5.1 still plaguing us!

Thanks for the response. I am glad you have replied in a constructive manner, i am used to people repsonding saying things like “that file format is rare, that frame rate is rare etc etc.”

The file is mp4; i choose this as i find it best for image quality for the size of file and also i use these on my main living room media centre which has surround sound . Perhaps i have just gone with it as my ripping software defaults to mp4.

The unit in question, is in my bedroom and is just connected via hdmi, nothing fancy inbetween. I just thought that it would downmix to stereo as standard, for all audio formats if you have selected stereo and are using just the tv speakers…

How hard would this be to implement do you think?

thanks
