I would like to share with my latest achievement: I've installed without any problem Blu Ray Recorder with ATA connector to my Pi1536. The recorder was manufactured by Panasonic (Matshita) and the model is UJ-220 and UJ-225 will run as well. It's running perfectly on my laptop and it's compatible with Pi1537 / Pi1556 / Pi1557 / Xi1526 / Xi1527 / Xi1546 / Xi1547 cause it's the same platform. All you need is unscrew one screw, take out the old dvd-rw drive, take out the bezel, put the bezel to new drive, put in the new drive and screw it back.
REMEMBER: You need WUXGA LCD (1920x1200) to watch FullHD movies!
