Microsoft’s Sean Alexander may have moved over to the Longhorn group (congrats, Sean!) and off the Media Center team, but he’s still posting good stuff at Addicted to Digital Media:
ATI’s new Home Theater 550 Pro-based ATI TV Wonder Elite TV Tuner board was just released and started shipping to retailers today. I just got my hands on a board and have personally seen the quality of this standard-def tuner beat that of an upsampled signal on a high end HDTV set from a major manufacturer. That’s saying a LOT. Thanks to the 3D comb filter, you don’t get the “jitter effect” you normally see on overlayed graphics such as a CNN or NBC logo or sports scorebox. I cannot wait to put this board through it’s paces personally on my MCE box this weekend.
The Imaging Science Foundation (ISF) has certified this board as meeting or exceeding specifications for high-end consumer AV electronics.
If what I’ve seen hold true, this board significantly raises the bar for other PC-based TV tuner manufacturers. I know ATI has been investing heavily to develop this card to exacting quality.
I used the previous generation of ATI’s All-in-Wonder cards (I still own two, in fact). They were OK for their time, but once you experience hardware decoding you can’t go back to slow, crash-prone, software-based decoders like the AIW series. Lately I’ve been working with Hauppauge’s Win TV-PVR series of boards. The most recent addition is the dual-tuner WinTV-PVR-500MCE, which is now in full service here. Every Hauppauge board has performed exceptionally well, and this one is no exception. I’ll have more to say about it later. Meanwhile, I’m eager to try the new ATI board.

I just installed the ATI TV Wonder Elite in my Dell XPS400 ,its the PCI version ,I had the USB version on my previous PC a P3 750MHz .My new PC is a XPS400 by Dell which has a 2.8Gig Dual Core Proccessor 1 Gig of DDR RAM 250G.B. hard drive DVD+/-RW and a DVD-ROM .Anyway when I attempted to install the software off the ATI CD supplied ,it did not install anything .Since I have the O/S WinXP SP2 Pro Media Center Edition 2005 ,I was told to configure it thru the Media Center ,which I did and it is working fairly well ,my biggest problem is I dont have any TV Guide ,however the Guide Plus System on my other PC the P3 is working and I can just update that GEMSTAR Guide Plus, I never really used the guide alot anyway .What aggravating me is with the USB version I was able to make the screen as small as 2″x2″ if I wanted to, on my desktop ,with the TV Wonder Elite I can only get it down to aprx a 6 1/2″ x5″ picture size .When Iam on the internet with TV on top ,I need for the screen to be smaller ,can you help me with this sizing problem ,I’ve tried changing the borders with the cursor with no luck and cannot locate any other way to resize the TV on my 19″ FP ?
Any suggestions or help greatly appreciated ,I thought the PCI TV Wonder Elite would blow away the USB Edition ,its starting to look like the USB is giving me more ease of use then this PCI card is !
Thanks Nick
