One thing to consider that isn't captured in the builds above is the TCO (total cost of ownership) associated with the Blu-Ray and DVR functions of Windows Media Center.
While $450 will get you the base hardware you are still going to need a Blu-Ray software player, generally $80-$100 on top of the $60 for the drive included in the hardware price. For the same price as the BR drive and software (around $150) you can buy a
stand-alone player that does plays movies as well or better and duplicates most media-extender type capabilities (video/music/photos from a PC on your network) and online features like Blockbuster/Netflix online, Rhapsody/Pandora, etc..
On the DVR/HD side of the equation you really have two tiers to deal with...
Basic ATSC/QAM "free content" tuning just requires some extra drive space and a pair of tuners... figure $60-$70 (already in the price of the systems we discussed).
If you want to view or record anything in the encrypted/premium realm beyond basic cable you need cablecards. Adding a cablecard tuner to your media center is going to set you back $300-$400 on top of the price of the basic system which puts you easily into the $750-850 range.
I did some shopping around and found Blockbuster is clearing out their Tivo HD Series 3 boxes for $99 (in store) and you can grab the WD DVR 1 TB extender eSATA drive for another $113 at buy.com. All-in you're looking at $212 for 140 hours of HD storage plus $13 a month for their guide services (first 3 months free are currently included). You also get access to the "extender" features like Blockbuster/Netflix online and the various video/content sites supported by plugin apps. The TiVo can also stream content from PC's on the same network and share shows with other TiVo's or PC's on the network...
While I understand the interest in a DiY project I think people who embark on the HTPC mission and want "premium" DVR and Blu-Ray need to be aware that it's not necessarily the most cost effective solution. With massive extender style feature convergence in pretty much much every gaming console, blu ray player and DVR on the market coupled with highly flexible transcode software out there I think the HTPC is losing it's shine. Don't get me wrong, I love the Windows Media Center look and feel but when you look at the total cost to own it's tough to justify the headaches versrus easy to use "closed box" solutions.
I'd love to see Microsoft converge the Windows Media Center concept with the XBox gaming console by supporting cablecard, blu-Ray and a Zune dock on the same device to create the ultimate living entertainment room appliance. It would make support of the platform a lot easier (hardware/software variances and nuances are still a PITA in Windows 7 MC, far improved from XP MCE 2005 though) allowing for greater market penetration and a huge value proposition. Scale of economy on production cost and the ability to more closely focus on a standardized hardware + software platform could really make it a cost competitive solution.. the guts to run any of the 3 devices (game console, BR player, DVR) are so similar it seems like a no-brainer to converge the 3 into a lower cost (than separates) single box solution with an appropraite DVR subscription model and app/content/extras store. If TiVo can get people to fork over $400 plus $13 a month for their Premiere box and Microsoft can get $300 for a gaming console + the Live! subscription I think there's room in the market for this sort of product.
Just food for thought.. guess I should find something more productive to do with my time than wax about the future of converged multimedia devices.
