Hi Dan,
openzaurus 3.3.6-pre1 comes originally with opie 1.0.3.
CoreDump made an Image based on Openzaurus, but with an updatet opie.
This was because the openzaurus people working hard on a new buildsystem, to make further releases easier. So opie development went on, but openzaurus was staying.
In future you can be able to choose between opie and gpe, that runs X packages.
Please have a look at the openzaurusnewsletters on the openzaurus website.
You shoul use the opiemediaplayer2 from the 1.1.3 feed in your package manager. This is working here.
Cheers,
Sam
