Are there any DVDs that actually have a DTS speaker placement test on it (commercial ones, like movies)? I have Avia already. All the ones I've found have been DD only. I was lucky enough to find some DTS .wav files here: http://www.sr.se/multikanal/english/e_index.htm one of which was a speaker placement test complete with LFE. If you're lucky enough to have a soundcard that passes through an unmolested bitstream (I use Winamp+Asio driver on my Waveterminal 192L) or you can burn them to an audio CD to play them. Some of the soundfiles on there are really cool. Even better if you speak Sweedish(which I don't). One or two in English. After burning a CDRW to find out that WinDVD4+ does not do multi-channel bass management (wouldn't decode a dts .wav right)for DTS CD audio, I can only assume it doesn't handle LFE for DTS DVDs as well. I would like to check that for sure. On the otherhand my Onkyo TX-DS595 does some amazing stuff with the DTS LFE channel (SPDIF out) . Surprised me at how well it works (I was never sure it did anything with the bass). Of course this makes the point of purchasing a soundcard with high quality DACs moot. PowerDVD doesn't appear to decode DTS LFE or any other multi-channel DTS DVD software. Lame. I live in an apt. so a sub is a definate no-no.
