The audio output format need to manually select during BD playback to output as non decoded high defination audio pass through to AVR. This is kind of manual tedious process i don like about it.
Other than that ... i am sactisfy with it
compare to my PS3 (80g) BD playback which dont have the bitstream function.
Try out the clonedvd to rip the BD as iso and mount it with Virtual clonedrive and it works exactly like a BD playback. Tested ripping the BD(44gig) less than 30 mins with LiteOn 8x BD rom. Thats cool !
Now i can have all my BD collection into HTPC and playback without the disk.
