well i find that the 5.1 audio on a mkv file is not as clear as dvd 5.1, especially DTS.

i find the mkv is a little muffled. unless im not using something which you guys are.
so some how i still go buy some nice dvd to watch.

using the Hardware decoding from my soundcard. the DD and DTS sounds much better, clearer and louder.

although i m very impressed with mkv able to carry 5.1 info..

the other thing i wanna ask. can the audio codecs output spdif into my soundcard so that i can use my soundcard to decode the sound.

if i use power dvd to play, i set audio output to spdif.

anyone tried spdif output for mkv ?
