Today i am going to buy A.C.Ryan in pc fair looks perfect for my vsx891 H . price around 619RM (not sure)
Dolby Digital 5.1 (pass-through & downmix to stereo)
Dolby Digital Plus (pass-through)*
DTS (pass-through & downmix to stereo)
what does "Pass-through and downmix" mean. does it support True HDand DTS HD
any suggestions ?
PC Fair price someone mentioned RM560/- in AC Ryan POHD thread).
Everyone is still waiting for Dolby True-HD and DTS-MA bitstream

. Downmix (in above mentioned case) means convert the source to stereo. Passthrough means bitstream to the AVR to decode. Note that this is only regular Dolby and DTS passthrough not HD Audio.
Currently when you select a True-HD source you will get a 'Unknown Audio Format' error. If you select DTS-MA you will only get the Core DTS 5.1 and not the HD format. This is more applicable to m2ts files which are direct rips from Blu-ray.
For MKV files (can be compressed from blu-ray rips as well) they can't support True-HD and DTS-MA so they include only the converted normal DD or DTS 5.1 sound. You shouldn't have problem getting normal 5.1 sound from these files on your 819.
