Building a Home Media Center with my Bang Olufsen instalation

I have a Bang Olufsen video and music system in my home. The central
system is composed by a the Beovision 5 42" plasma TV, a BeoSound 9000
CD player, four loudspeakers and a subwoofer (Beolab 8000, 6000 and
1). It work as a complete music system and home theater with dolby
digital 5.1.

This central system is connected to three more rooms equipped all with
two BeoLab 4000 loudspeakers each and a Beolink to use the remote unit
all over the house.

Now I want to connect a new PC to use as a Home Media Center to the
B&O central system. The features of this PC Home Media Center a

CREATIVE SLIX PC MODEL MPC51C3 with Audigy sound card
Intel Pentium 4 3,06GHz processor
250 GB UDMA Western Digital hard disc 7200 rpm
PLEXTOR PX-708A DVD burner
ATI ALL IN WONDER 9800 PRO graphic card

The purposes of this PC a

- Music and video download from Internet
- Hard disc downloaded music and video play thru the whole home B&O
system
- WEB Radio playing thru the whole B&O music system
- Digital Pictures server to see on the TV
- Camcorder Video editing and playing on the TV
- Slide show editing, burning on DVD and playing on the TV

The ATI ALL IN WONDER 9800 PRO graphic card brings lets do all video
described tasks as far as I know. It also includes a remote control
that makes things much easier when you want to control all this from
your armchair in your living room.

I imagine that the Audigy sound card will let me add AC3 sound to my
home videos and slide shows to play after on the home theater.

Can any experienced of you tell me if all this will work?
