HDTV Wonder & DTV Player - Quality Upgrade
You may notice that in the DTV player, you get black bars in the window; this is because not all content broadcasted is actually HDTV content. Commercials, generally speaking, are not in HDTV resolutions, but they are in some sort of a DTV resolution (either EDTV or SDTV), so broadcasters have to add in black bars to maintain a native HDTV resolution. This is why you get black bars in the window sometimes. This rule applies to DTV programs that are also in EDTV or SDTV resolutions. If you own an actual HDTV set, you don't see these black bars because the HDTV manufacturer includes coding that manipulates the image into the native 16:9 HDTV resolution.Technically, commercials are converted from an analog format to a digital format, but they look better in a DTV environment because analog viewing generally has noise/interference that makes the signal look worse. You can see the difference particularly when you get to instances of commercials using bright colors.
Keep in mind that we are capturing a HDTV screenshot at the native 1080i resolution (16:9 widescreen) with a roughly 65% to 71% signal strength, and analog TV streams via analog cable at the standard 640 x 480 (4:3 ratio) with a ATI All-in-Wonder 9600 Pro on another system. If you are watching TV full screen with the TV player at 1280 x 1024 on your computer monitor, the computer scales it upward, which is another reason why TV looks poor on a computer. If you watch DTV on your computer, you are most likely scaling down because at 1080i, the signal is being broadcasted at like, 1920 x 1080. This is the same effect that you get when you start with a picture at 800 x 600 and try to either enlarge it or make a thumbnail.

Analog converted to digital programs also follow the same rule. People look better and more distinguishable, but you still will run into the bar issue with analog to DTV converted programs.

How does this compare to the MyHD2I have this card too. but I'm dualbooting WinXP64 because they don't have 64 bit drivers. I figure ATI will be more likely to make 64bit drivers

Fact: There are several companies making HD Tuner Cards. One of the major cards out there is MyHDhttp://mcm.newark.com/NewarkWebCommerce/mcm/en_US/...
"In fact, the only major company that we are aware of making an HDTV tuner for PCs is Hauppauge, but the WinTV-HD hasn't sold in the same volumes for Hauppauge as their analog WinTV tuners. Add in the vacuum of HDTV supported multimedia software (MCE, Beyond TV, SageTV, Multimedia Center, Forceware Multimedia, etc...), and you get a recipe for a PC market not ready to embrace HDTV technology."

#12 - 480i is the approximate quality of analog TV broadcasting. As for the tubes in some of your TVs, some do display the signal in a lower res, like 512x400. There should be several websites that have this in their information docs. Try "analog tv 480i" in google or something. So we are both kind of right… :)#13 - I think you make a good point, and this was something I was debating myself. My consideration was based on three other points: pricing, availability, and future software support. On the pricing issue, HDTV Wonder is at the cheapest pricing point I have heard of for a PC HDTV tuner. No other HDTV tuner can be bought or will be able to be bought at a retail store for the near future, at least according to our last talks with the stores a while back. And future software support is something that a company like ATI will have to do in order to keep their product in retail stores (i.e. EazyShare DTV). Hope that explains our line of thought a bit more.

My take on the card - it had better be darned good/stable/etc for me to pay 200 dollars on a non-hardware HDTV tuner card. I bought a DVICO FusionHDTV last year (or maybe before that) and it was only 140 bucks or so.mcveigh - Tuesday, June 22, 2004 - link
this is too limited to have earned an editor's choice.Andrew check out what the people at avsforums thinkof the card and it's competitors.

I've only read to page four and I'm not too impressed with the article so far. It seems that a little more research should have been done or something before bringing the article to print. Hauppage isn't the only company bringing HDTV tuner cards to the market. I haven't been interested in HTPC's in a year at least, and I remember looking at products from MyHD and buying a tuner card from DVICO (their original FusionHDTV).I stopped reading this article after reading that analog signals are 640x480. It's been a while since I've researched this topic, but I know this is not true.

AndrewKu - I'll have to give MMC 8.8 a try. EazyShare looks really cool...does it require a good video card to run the server? I have enough spare parts to build another box, I just need a motherboard and a cpu ($29 for a cheap mobo off newegg and about $50 for a 1.8ghz athlon). I don't want to blow another $100 or $200 for a video card for a server tho.Also, should I install the latest version of Catalyst, or should I install 3.x like in the MMC article?

#2- It cannot function as the second device to support PiP/MultiView, but it should in a later release of MMC.#6 and 8 - You are sending a digital signal of a digital signal to your digital monitor. DVI output comes via your video card, not the HDTV Wonder as #7 mentioned.
#8 - If you are talking about PAL support, this is an NTSC version. As we understand it, this is for the North American market only. This isn't really for the gamer per say; this is just a nice way to get DTV into your home without having to pay the expensive cost of a HDTV. And yes, you can just plug in an antenna to the RF connector that is what I mentioned in the review. An antenna is not necessarily analog or digital; it is the signal that is categorized as such.
#9 - If you are having trouble with EazyShare, you might want to try looking at our MMC8.8 review. We worked out and tried to manipulate every single bug occurrence. In our experience, your system configuration should be stable with MMC and a TV Wonder Pro. Though, I am not sure what your specific issues are.

I have an ATI TV Wonder Pro with Remote Control...the only thing good about it is the remote control, lol. The TV software was fairly buggy for me, plus the required specs aren't really true - I had a 1.4ghz Athlon, 1gb ram, and a radeon 9600xt, and it'd still skip while recording if I even opened Internet Explorer. That and I didn't care for the GUI.I hope ATI has a trade-up program for their TV tuners like they do their video cards...anyone know if they do? I may go with Hauppauge next tho...their USB2 TV tuner is looking pretty good.

A few pretty basic questions from France, where DTV lags the US:Reception: can you just plug in an antenna to the digital jack for capture?
Will it work in Europe, too?
Can you use a 9600se card & still get the noted benefits? This is an extremely expensive solution ($400 USD or 500 Euros) for us non-gamers, btw, though a tidy racket for ATI.
No DVI? So then you're sending an analog version of a digital signal to your digital-capable monitor?
You mention Hauppage's DTV tuner, it would have been nice to have known more about its capabilities & how it compares & sacrifice a few photos of the tuna salad surprise.
