Not trolling. Just pointing out that not all that glitters is worth $99.

I'll tell you why I want this: I want to build a cheap TiVO like unit. I have an old p2400 right now that's acting as a VCR using a Hauppauge WinTV PCI card and Snapstream to do the capturing. It's hooked up to a TV with a VGA input installed.
The problem I have right now is that I cannot playback and record. Would a faster machine fix this? Err possibly. That depends. Both capture and playback are time dependent. If I had a dual proc machine available for it, it'd definitely work.
I'm not building a more powerful box if I can just buy a $99 card and plug it into the one I already have running. As a matter of fact, I'm trying to find the info on how to buy one of these cards right now.
Incidentally, if you're interested in a reason to buy one of these doodads if you have a more modern machine: I, for one, watch a lot of vids on my computer. As I said, I have that capture box acting as a vcr right now. While I'm browsing the web, I watch the shows I've capped in a little window. Unfortunately, the vids do cause little lags in my machine. If I scroll in IE, sometimes it'll lag the video. Is that something I should pay $99 to fix? Hmm I might, but I don't expect anybody else to. However, I have one more interesting twist to throw at this. I have a 13 inch TV doing nothing right now. I could place that TV right here on my desk off to the right, and the card will decode to it.
Now that is totally cool. If I'm at my computer, it makes it trivial to pause the video or fast forward through commercials. I could see people who download lots of stuff from P2P really enjoying this card.

There are only so many mp3 players, keychains, and paperweights that can be useful with all those old processors that people have laying around.
This board should therefore do very well in the home-brew market.

People keep saying this, over and over, for the last, oh, let's say ten years or so. And people, no matter how snottily they may say it, have always been wrong.
History in fact shows a strong trend in the opposite direction, for better or worse. Winmodems now run off the CPU. The whole "PCI" soundcard means roughly that the soundcard is just a prettified ADC and DAC on a card, with some assorted supporting circuitry. Not like an Adlib card, which did everything on board, back when a computer couldn't simulate even FM sound in any reasonable amount of time, let alone multitask. Movie decoding is moving onto the CPU, and staying there. (Three or four years ago, you had to get a hardware decoder. In another couple of years, this product notwithstanding, they'll be largely a thing of the past.)
Integrated motherboard video graphics w/ AGP directly sharing the system memory means that the CPU does slightly more work shuffling around memory in 2D mode, even for graphics cards.
The only reason graphics cards remain seperate is that our need for speed is such that the graphics card is often more powerful then the CPU; if the general-purpose CPU tried to keep up with a 200MHz Geforce 2 or 3, it's anybody's guess how many GHz the CPU chip would need. I'd guestimate around 5 or 6, running at full power, maybe more, and of course that's 100% utilization.
Upshot, this device is fighting market trends. My measly Duron 800 can encode with xvid at roughly 1/3 real time speed (everything I have is Duron-optimized courtesy Gentoo); it's only a matter of time before that gets to realtime for the majority of people.
(That would be one advantage of Linux TiVo-like software products: The ability to use DiVX, instead of MPEG, blowing away TiVo's recording capabilities.)

This card does have it place. I use mine to play out to a TV while I do other things. My friends can watch an archived movie/tv show (encoded in DivX or MPEG2), while I do other things. And the picture/sound is flawless. Other times I have used it for "VJing" at parties-- showing music videos while people dance to the music. The remote control works great, and doesn't work with just their own player-- you can get remote selector and use it to control winamp and powerdvd as well.
And, of course, if the manufacturer goes out of business, or looses interest, or doesn't support the same favor of M$ software that you want to run, you have a hundred dollars worth of junk.
Couldn't the same be said about any hardware manufacturer? I'm sure they'd have some sort of contingency plan for situations like that. But until they do go out of business, why worry about it?
Unless you're complaining about lack of drivers for other OS's (ie Loonix/BSD).. if so, I can't help you there. Most manufacturers don't want to provide support or drivers for Linux because it's not a "mainstream" desktop OS (and in my opinion, it shouldn't be; it's not ready.) Anyhow..

Anyone who has ever dealt with Sigma Designs, Real Magic, et. al. knows very well why the external, analog overlay is there. It's there for one almighty reason: DVD CCA licensing rules. There is zero chance the decoded content can be "stolen" in digital format. Rumor has it, even the external SDRAM on the card doesn't hold the decoded data during playback. Where I live, that's called "paranoid."
