MCE TV Tuner Roundup: Featuring ATI's Theater 550 & NVIDIA's NVTV

The Test
Testing TV tuners, especially comparing based on image quality, is a tough thing to do; the main problem is that there's no good test scene that's repeatable across multiple systems. Testing video capture functionality is easy. Simply play a non-encrypted DVD over and over again and compare image quality - but you can't really tell a TV channel to put its contents on repeat so that we can see how the same scenes look across 6 different TV tuners.
Using something like cable on-demand doesn't really work either because then, you're left using an external tuner to actually get the signal, and simply test, the TV tuner's ability to capture an external signal, not receive and tune a cable channel.
Luckily, there are two TV channels that are perfectly designed for the task at hand: CNN Headline News and The Weather Channel. Both of the aforementioned channels repeat their content, usually every half hour, for several hours at a time. Armed with 6 TV Tuners and a Sunday of nothing to do but watch the same 30 minutes of headlines over and over again, we had our test platform. Even after doing this, it's still tough to get frame for frame, identical comparisons across the TV tuners. So often times, we'll resort to using different scenes to illustrate strengths and weaknesses of the TV tuners. Rest assured that our findings came to be after spending quite a bit of time with each one of these tuners.
CPU utilization wasn't a concern, as all of the tuners ate up less than 7% of our CPU while recording. Given that you can't really run Windows XP Media Center Edition without a fairly fast processor and that all of the cards compared here today are full hardware MPEG-2 encoders, there's not much to talk about with CPU utilization.

That all changed when Microsoft released Windows XP Media Center Edition. Bringing the first true 10-foot UI to the PC...Whilst I don't generally like to nitpick too much, I really do find the lack of attention given on this site to Linux solutions a bit puzzling. Linux really isn't all that hard to get going, particularly for enthusiasts. And Anandtech does aim, I believe, to cater for enthusiasts.

I have the ATI HDTV Wonder, but I haven't built nor bought a MCE PC because I'm waiting for more confirmation that it will work with my HDTV Card.Also, if I'm not mistaken, it comes with a standard TV Tuner as well, so this article confused me when it said I would need both.

Something to keep in mind, if you have any thoughts at all of using MythTV at some point instead of MCE, you probably want to stay as far away from the ATI cards as possible. Hauppaugue cards have very good drivers, support and knowledge base for both MythTV and Linux in general. ATI TV cards... mmm... not so much... Then again, there are already HDTV based Linux cards with pretty good OTA and QAM capability fully supported under MythTV. You may not even need a crappy analog card. Although a PVR-150 will probably be useful for a while with those obscure analog holdouts on the far end of your cable listings.ChiefNutz - Wednesday, April 13, 2005 - link
Finally, Someone did a comparison review with several cards!!! I've been waiting for ever to see tests run against that ATI Elite & the Hauppauge / NVTV forever.. I do agree with #19 though... but i thought MCE 2005 doesn't support mpeg 4 anyways.. Thanks anadtech for fullfilling my wishes!!! yesoverclockingoodness - Wednesday, April 13, 2005 - link
#24 (Cygni): I agree with your comments, but I disagree with your ideas behind AnandTech. AnandTech is a business, and a successful one at that. If I am not mistaken, AnandTech makes at least $1.2 million a year from ad revenue.And for Anand and his editors, this is a full time. It's not a hobby anymore. :)

So... Which one of these cards features Win64 drivers...?--
Rune, soon to enter a TV-free reality...

Im glad I get to battle through 30 "OMG U LEFT OUR PRODUCT X, THE WHOLE REVIEW = WORTHLESS" posts in every single AnandTech comments thread.A) The PVR-250 Retail is $140 on Newegg.
B) The 150 ISNT IN STOCK at Newegg or Mwave, and has barely been on the market at all. Again, it takes time to write a review and do all the hours of testing required (especially when you realize that THIS IS A HOBBY to everyone who writes the articles). If the card isnt available, or has barely hit the market, how is AnandTech going to have it for a review started weeks ago unless somebody sends one?
C) And ya... if it aint on Newegg, Mwave, or ZoomZipFly, i dont count it as a real price/availability. ;) Call me crazy, haha.
Cant believe how much some people complain about a free website run by volunteers just trying to help people out...

One of nVIDIA's former Executives used to be a big wig engineer at LSI. Now can any one tell my why nVIDIA's solution is using LSI's silicon? Hmmmm....
