Yes, DVD-A is confusing. To be a true DVD-A disc, it should have a high resolution soundtrack using a 24 bit word length with sampling frequencies from 48khz to 192khz. They can be any number of channels, from 2 to 6. The true DVD-A layer is only playable on a DVD-A player.
These discs can also have DD 5.1, stereo and possibly even DTS tracks that are playable on any DVD-V player. You have to look closely to the wording on the box, and even then they may be incorrect.
The Eagle's 'Hell Freezes over is a DTS recording that also has a PCM (stereo) soundtrack. It is not a DVD-a disc.
This explanation is not meant to be all inclusive, just some basics.
