I've watched subtitled anime on Netflix. I watched the first 5 eps of chrome shelled regios and its dual audio on there. Hit pause, and then select audio options at the bottom. Japanese version with subs is available for quite a few series.
Ive noticed on pc you can click a button on the progress bar to switch languages... generally it will say English/Japanese before hand in the description. I remember Inuyasha and Naruto were sub only when they were on there.
