Which Blu-ray DVD player stream Netflix?

The answer to this question is changing rapidly these days. My suggestion would be to check out the netflix website. They have a list of digital media players that can stream info from netflix:

However, these devices are getting most of the attention right now:

LG Electronics has introduced the first networked Blu-ray Disc player with the integrated ability to access and play back Netflix instant-streaming video content: LG model BD300.

Samsung's connection to the Netflix service will work through two Blu-ray models, the BD-P2500 and BD-P2550, that have already been on the market. Consumers who already own those Samsung models will need a free software upgrade to make the players compatible with Netflix's streaming service.
