I can't explicitly answer your question - your profile does not include any location information. Here in Silicon Valley we have lots of PC integrators - mostly run by Taiwanse, and on practically every street corner. OEM parts are sold over-the-counter for very cheap prices.
The Hollywood+ is also sold in retail packaging with the name changed - but look for a logo that says "REALmagic Inside!". This will probably cost more than $40, and sometimes they throw in the Remote Control which normally costs another $20 on the Web. The LEAST desirable way to buy the board is in a Creative Labs DXR3 DVD kit - because they change the PCI product ID and then you must use the Creative Labs software which is updated far less frequently,
You will need a free PCI slot - but nothing else, as they will give you stereo audio and S-dideo cables and an S-video to composite converter, plus the manual and the CD-ROM (actually, the last one I used came with a "free" movie on one side of a DVD, and the software on the other side of the "flipper" DVD). Once you get the projector up again, you may want to forego use of the passthrough VGA cable if you notice ghosting (which doesn't always happen) - but I've got both WinDVD (for movies) and CineMaster (for video DVDs) and the Hollywood+ all on one HTPC, no conflicts. Good Luck!
