The other day I went all out to compare DTS and AC3 files and how they sound on my system.
For this I used two setups:
– A WD LIVE Plus unit connected via HDMI to a Sherwood RD-8504 AVR with the HDMI monitor going to a Sony Bravia XBR something model 
– A WD LIve Plus unit connected via HDMI to a Vizio TV.
So, I captured some video clips from an outing. I encoded it with Handbrake and made a nice MKV with no audio.
I opened Sound Forge and made 5 mono waves with music and narration. Then I made an LFE mono wave from a track I borrowed from The Matrix LFE track to add the rumble and all that.
I got the 5.1 mono waves and using Minnentoka Surcode DTS encoder I made a DTS 5.1 file. With the Surcode Dolby Digital encode I made an AC3 5.1 file. I used, of course, the same 6 mono waves.
I added the DTS and AC3 files to the MKV file using MKVMerge.
Then I ran the MKV file via the first setup with the Sherwood and Sony. WOOOOOOOOOOOOOOOOOW! Now I can see why people are complaining about issues with DTS. I am a BELIEVER :D My whole room vibrated with sound when I switched to DTS track. The AC3 track was fine but it was just FLAT surround sound.
So I thought about posting this, because I am SO IMPRESSED with DTS. GEEEEEEZ!
On the second setup with WD unit connected via HDMI to the Vizio, both tracks were flat of course. For DTS playback VIA TV I had to switch unit to Stereo for DTS to play via TV speakers in both setups as expected.
DTS is truly amazing. I can not listen to any audio now via TV speakers :D because I spoiled myself :) Life, ladies and gentelmen, will never be the same after that. Nirvana!
