I've been mute about this for a while, but I figured I should report it. My BlueRay DVD drive combo has a number of quirks that need to be worked out with ata(4): - It plays audio/data CD media perfectly fine, and data DVDs perfectly fine. - It doesn't play region locked DVDs, but it will play region unlocked DVDs (mplayer, vlc). - It suffers from frequent burn errors (burncd, cdrecord, growisofs) during the burn process (not the fixation process). I've seen complaints about the firmware maker (Matsushita) on some mplayer sites and how the drives suck, but they were complaining about region locking, and this issue with the drive appears to be centralized in a more ata specific way. I'm using an extremely up-to-date CURRENT (today, 4pm), and I've seen this issue occur with 7.0-RELEASE, PC-BSD, and 8-CURRENT, so I doubt that the issues are regression related. The idenf for the drive is: `HL-DT-ST BDDVDRW GGC-H20L 1.03'; a link to the specs sheet can be found here: <http://us.lge.com/download/product/file/1000003670/h_ggch20l_spec_sheet.pdf >. They don't have a product page though and it wasn't listed on the website :(. Will provide more data as requested. Thanks, -Garrett
