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.

Interesting that the NVTV card here got the worst review and over at tech report got the best.I wonder if it has something to do with one being a dual tuner and the other well not.
Yeah bummer to not see the 150mce (and it's been in stock everywhere for a while, it's not in stock at newewgg cus they keep selling out, try amazon or buy.com)
Also I have to question the reasoning behind using actual cable TV for testing. The quality can vary so much, and we of course can have no expectation of what type of quality could be coming from your cable signal vs ours.
Use of some type of modulator to create a catv signal or a game system (like TR did) would seem to be a better choice to me, plus you could test with testing patterns.

Oh, I would also go to the following website if you have a hauppauge card: http://www.shspvr.com/This site has more current drivers for the Hauppauge cards, plus a pretty good forum with useful info. If you get the 'beta lite' cd packages for your card you get a easy to install driver package.

#48 I don't have digital cable but my understanding is that they can. The one thing you will need however is this: http://www.pcalchemy.com/product_info.php/cPath/38...and thats needed so you can change channels with the cable box.
I have a pvr-350 with gb-pvr and I couldnt be more happy with it :)

Ok, I admit I'm a total noob when it comes to TV tuner cards. I've been looking at them for awhile, but can't get my ahead around what they can and can not do with regards to the signal source. I'm always a bit disappointed when TV Tuner reviews don't exactly describe the video source used for the tests (analog cable, digital cable, aerial, cable company, etc.).My impression, which in all probability is wrong, is that these cards require an analog source and that they can not be hooked up to a digital cable source (such as I have from Comcast). Is this true, or can these cards be used with a digital cable signal?

i agree with the posts that 150MCE should've been included... great price/performance ratio for that cardto the freak that said 150MCE isn't widely available.. ur a dumbass! i can even buy one RIGHT NOW in freakin CANADA...
so yea Anand, ok review, but it needs 150MCE badly

I swear no matter who reviews these cards, the results are always completely different. Some people find the NVTV cards to be terrible while other sites give em editors choice and the forums have equal amounts of hate and love for all the cards. Ugh, I'm ready for cablecards, I don't want to think about analog and IR blasters ever again... Cmon 2007!jamawass - Wednesday, April 13, 2005 - link
Volunteer website? Do you know this site was valued at $100 million at one time? This is a business dude. BTW What happened to part 2 of the Myth TV review?WooDaddy - Wednesday, April 13, 2005 - link
Just to let everyone know, the eMuzed Maui has NO third-party support other than MCE. I had one and couldn't get it to work with any other app out there including sage and snapstream stuff. I ended up picking up a Prolink TV7000 instead. Compatible with the Hauppauge PVR250. Works flawlessly, but difficult to find.DigitalWarrior - Wednesday, April 13, 2005 - link
#36 (GoatMonkey) - For software to review, don't forget SageTV! This is superb PVR software.Good warning #28 (Kishkumen). A lot of 3rd party PVR software doesn't have support for ATI cards.

The PVR 150 should have been included in this review - it seems like the best tuner out there for MCE. I suspect the outcome would have been different if a '150 was tested instead of the 250.
