I stand corrected; the manual only states its DTS HD (whatever that might be). Now someone explain to me the difference between DTS HD and DTS HD MA ?
As best as I can tell DTS HD includes two variants: DTS HD MA and a slightly compressed variant DTS HD HR for space-challenged discs. My meager disc collection includes movies with DTS HD MA and DTS HD HR, both of which play just fine in DTS-HD mode. The DTS HD MA discs sound better subjectively, but that could be that expectation thingee at work.
Some websites suggest DTS-HD had been renamed to DTS-HD Master Audio, perhaps after the LG manual had been printed up) but if that's incorrect, I'd like to know.
BLU RAY - 53+PE (if your quantity is zero, you are missing out on too many movies)
HD DVD - 10 (if your quantity is zero, you are still missing out).
