nVidia has ATI beat in the 3D department and is trying msucle in on their "all in wonder" turf. But just like nVidia spanks ATI on 3D, ATI returns the favor in the video capture/encode department.
Simply put, ATI has dedicated custom hardware for NTSC video capture, a pretty decent comb filter and a great implmentation of the Ligos GoMotion MPEG2 codec.
The ONLY weak spot is their capture time de-interlacing which is a bummer for those of us with progressive displays and I think that is fixed with the 8500DV All In Wonder. We shall see. I think the 8500DV will cement ATIs position as the ultimate HTPC card vendor.
I have the nVidia "personal cinema" at work and it SUCKS. Nice 3D though. It's just a cheap capture setup bundled with WinPVR(DVR?) which is downright awful.
I too have been looking for a device like this that would combine the 3D horsepower of the GeForce and "Tivo-like" capabilities and I was encouraged when Maximum PC chose the Personal Cinema for its Home Theater rig a couple months back. Unfortunately, the end-user reviews that are coming out on the Personal Cinema models aren't overly glowing as of yet.
I'm tempted to wait for the AIW Radeon 8500DV, but I've heard so many bad things about the drivers that it's hard to make the plunge. If you're considering the 8500DV as well, you can find a review on the 8500 from AnandTech here: http://www.anandtech.com/video/showdoc.html?i=1544
Best of luck in your quest, hopefully somebody will get this right one of the days...
