Sony Playstation 3 Blu-ray DVD Remote - CNET
CNET have published their review of the Sony Playstation 3 Blu-ray DVD Remote which should be of interest if you do a lot of movie watching with your PS3 and don't mind the extra expense. 'The remote, like the wireless game controller that comes with the system, features Bluetooth wireless connectivity. In fact, it behaves just like a Sony wireless game controller would, except you have to manually pair it to the system via the accessories link in the settings menu (it uses port number seven). However, once you've paired it, you shouldn't have to worry about doing it again.
There are certain advantages to Bluetooth technology, the biggest of which is you don't have to deal with the line-of-sight issues you encounter with IR (infrared). For example, we pointed the remote in the opposite direction with our back to the system, and it still worked fine. The remote also is very responsive with virtually no lag time between button press and onscreen action.'
