[Eee Pad Transformer Android Development] shredbeta:
Went back to 4.4.4 for a while and it was all good. Have now flashed Lollipop #17 and still have the same issue with Google Play Movies. Have done a full wipe each time and tested before installing any other apps.

Found the following in the logs during my most recent test:

I also found some threads elsewhere on xda where people with this problem were missing /system/vendor/lib/mediadrm/libwvdrmengine.so and /system/vendor/lib/drm/libdrmwvmplugin.so. While I have libdrmwvmplugin.so I don't have libwvdrmengine.so.

Thoughts?
