Addressing the initial request on this thread about which BD player to use:
The Beosystem 1 currently offers IR control of the Sony, Samsung, and Panasonic Blu-Ray players. I should think that the BS3/BV7 will offer even more options for compatibility. With the Beo 5, you can program the inner and outer directional buttons on the round part of the remote to directly control the menu navigation and ff/rew/chapter up/chapter down navigation.
The Playstation 3 is an excellent BD player, in my opinion, because Sony does a nice job of keeping the firmware updated to keep up with the latest Blu-Ray features. Also, the PS3 now supports divx (but with some limitations in compatibility). With a Lintronic device and a third-party IR adaptor, you can get around the drawback of the PS3 lacking an IR sensor. However, it's still not possible to power the Playstation on and off through IR control.
Something worth waiting for and watching is to see if Microsoft adds an inexpensive Blu-Ray external drive for their Xbox 360 (which they are rumored to be planning). The Xbox 360 has an excellent library of HD downloadable movie rentals. As downloadable content is expected to be the future of HD, this solution would give you the best of both world. Also, the Xbox 360 supports divx -- even more reliably than the PS3 does.
When and if (let's hope for "when") B&O provides a Blu-Ray player, this should offer some unexpected benefits. The BD format requires that all future BD players have the ability to connect to the internet via ethernet. This will enable firmware updates from B&O to be performed by the user at home -- no longer requiring expensive service visits from our dealer for firmware updates. Also, an internet connection could offer many extra features -- such as accessing CDDB for info about the CD/DVD/BD disc that is playing.
