DVD-A questions: LFE channel; DTS/DVD-A confusion

I am recently into DVD-A, only 10 titles to date. It is somewhat of a steep learning curve, finding out I needed an ICBM and 12 expensive interconnects just to get off the ground (music companies used to have my sympathy, but no longer). Now I am being confused on formats. I ordered a DVD-A of Hell Freezes Over and got a DTS recording instead. I sent it back, but not sure if it contained DVD-A format or not. No mention on outside. Is there a combined DVD-A and DTS version available? No word yet on my return. Then I got some classical stuff, Brahms 2nd and 3rd Symphonies from old Vanguard recordings, and the LFE channel has apparently LF garbage - miscellaneous thumping that has no relation to the music tracks - perhaps out of sync? Can only listen with the LFE control on the ICBM all the way off. What's up with that? Anyone else have a similar experience? Doesn't happen on any other of the DVD-A recordings. I get the feeling DVD-A is still on the bleeding edge.
