only ones I have tested and worked are in DSL710/720 and DRL 200 that Meridian used; they are hit or miss on eBay (50/50 its bad). tested a bunch of IDE drives from older posts in my G91/98, none of them worked at all. would think Bluray would be a no go, doubt what ever video/audio chips are in the G series/800 would be able to take that data. with the G91/98 more concerned about them frying themselves, have spare drives but not boards when they do decided to die. who knows, its always possible something newer may kind of work, toss something in and see! worse comes to worse you have a nice chassis you can make into a Bluray player.
