I took a brief look at a few digital content licence agreements (Amazon, Netflix, Hulu, Marvel comics, etc.), and none of them try to do what I think you are trying to achieve. Instead, they used defined terms to sidestep the problem you are having.

For example, from the Netflix Licence Agreement:
Netflix provides a subscription service that allows our members to access movies and TV shows (“Netflix content”) streamed over the Internet to certain Internet-connected TVs, computers and other devices ("Netflix ready devices").

Note the use of the term "Netflix ready devices". The other licence agreements I've looked at do roughly the same thing.

So, to answer your original question:
I think "playback device" is fine. Just "device" is also fine.

To take a different approach to the problem you are having:
Instead of trying to come up with a word, it might be better to list out the categories you have in mind, then make it a defined term. For example:
"CD players, DVD players, personal computers, television ("Devices")" (or "Playback Devices", if you prefer)

Then for the rest of your specification, you can just use the word Devices and not have to worry about whether you have picked the right word or not.
