The 96/24 signal that you are referring to is the digital signal from the optical or coaxial output of your DVD player. As you have ascertained, not all DVD players can output a digital 24/96 signal and this applies to HT processors/amplifiers/receivers, only a handfull of these devices can accept a 24/96 signal. Therefore, purchasing a DVD player on the merit that it can output a 24/96 digital signal is senseless, unless you have a HT processor that can accept that signal. As long as the player can play 24/96 disks like the ones from Chesky, then you are covered.

All the current generation of DVD players are using 24bit DACs with a sampling frequency up to 96kHz and that should be your minimum criterion for selecting a DVD player. THe 24/96 specification means that the DVD player can decode/play any software that was recorded using 16/20/24 bits with a sampling frequency rate of up to 96K, e.g. CDs are recorded at 16/44.1; most DVDs @ 20/48; Chesky DVDs @ 24/96. At the end of the day, you will have to evaluate the quality of the player by listening and viewing the unit. Specs will not tell the whole story.

The reason why most players downconvert the digital signal is because the 96k is not the standard. I believe it also has something to do with the copy protection scheme that does not work with a 96k signal i.e. it bypasses the copy protection mechanism if the signal is at 96k. Maybe someone else can elaborate on this topic.
