TV Tuner Comparisons
In this section, we'll look at how the ATI Theater 650 compares with the NVIDIA DualTV MCE and the ATI Theater 550 Pro. As in the past, we will be looking at power consumption for these cards as well as image quality, but for this review we will be adding a section on CPU utilization to see what kind of overhead is associated with using these cards.
Power
For power, we tested each of the three cards at four different states: while the system was idle, while watching live TV, while recording live TV, and while watching TV while simultaneously recording the broadcast. Here are the results.
For reference, the power draw of the system without a TV tuner card installed was 145 Watts. We can see from the table that the Theater 650 and 550 drew less power than the DualTV overall, which makes sense given the DualTV's dual tuners as opposed to the other cards' one. We can also see that there isn't a very big difference at all between the power consumption of the Theater 650 and 550, and interestingly, there wasn't a difference between the power load of the system while watching and watching/recording with the Theater 650.
Channel Switch Speed
We again wanted to see if there was any difference between the channel switching speed of the different tuners, as the different hardware can sometimes affect this aspect of the tuner. Here are the results.
As the data shows, there is again not much difference between the Theater 650 and 550, and each of these cards took around two seconds to switch channels (the 650 being very slightly faster). The DualTV took about a half a second longer than the other two making it the slowest of the three. As we mentioned in the last review, two seconds may not seem like much time, but when trying to flip rapidly through channels, the delay can be very annoying. Unfortunately, it appears that the new "mini-can" tuner of the 650 doesn't substantially improve the tuning speed relative to the 550.

htpcnews.com and thegreenbutton.com would be two good places to start. There's no card available in the US that can tune a satelite signal directly - they all rely on the set top box connected via s-video. Any of the cards reviewed here, or the Hauppauge PVR series will be able to handle that task.vailr - Wednesday, June 14, 2006 - link
I'm using a TV Wonder Pro, which has much less tuning lag time than the 2 seconds shown for the Theater 650. Maybe: mention alternate choices for those wanting a TV card with less tuning lag time. An exhaustive TV card review would include ALL the various ATI cards, the Hauppauge cards, Avermedia, MSI, nVidia, and several of the high-end HDTV cards, such as the Fusion HDTV. (Some are designed to only work with Windows MCE). There's even a "Linux-only" TV card available. Suggestion: Maybe, partner with Newegg, and do a mini comparison review of every TV tuner card available thru them? And ending with an "Editor's choice" TV card.pjladyfox - Wednesday, June 14, 2006 - link
I'm going to second this idea. A nice TV Tuner card roundup, covering ALL, available cards thru Newegg would be something I'm sure a lot of people would be interested in; possibly even asking for suggestions on questions to focus on for such a roundup.darkfoon - Wednesday, June 14, 2006 - link
Thirding.I have a hauppauge WinTV 250, although I wish I had something that gives me more control over the denoising aspects, or does better denoising (My signal quality is entirely dependant on whether Comcast feels like screwing its standard Basic customers on any given day)
I'd really like an article that compares even cards that I don't know about; cards that could better suit my needs.

I usually look forward to reviews posted on Anandtech due to the depth and detail provided but this one has got to be the worst one I've seen to date. Here's just a sample of questions and details that should have been covered:a. Why was there no mention and/or details given in regards to the DRM hardware that has been mentioned in the press release?
b. Why was this card not paired onto a system using a X1600-series video card to test the AVIVO integration?
c. Why was there no details given about the Catalyst Media Center beyond just it being a footnote?
d. Why was there no details given about other PVR software, such as BeyondTV, support being available?
e. Why was there no details given in regards to capturing from other sources, such as VCR's, from the review?
f. Why was there no details given in regards to the MPEG-4 hardware utilization during the CPU testing?
I mean, Goddess, I could go on and on about just what was missing from this article but I'm sure many more will ask the same question; was this truely a review or just a PR article?

bad news I found out that the 650 dosen't have a hardware trasoncoder it using ref to Soft Avivo Video Converter so there for MPEG4, DivX, WMV9, H.264 it done in REALtime Hardware

Pardon my language but WTF?! Then how the heck are they able to say that they are Microsoft Vista premium logo ready??Here is a snip from a Dailytech article at http://www.dailytech.com/article.aspx?newsid=2842">http://www.dailytech.com/article.aspx?newsid=2842:
----------------------------
The following are requirements for Windows Vista Premium logo-compliant PC and will be mandated by June 1st, 2007:
* Must have H.264 hardware decoding
* Must have HDCP
* Must support multi-monitor support
* Must have HD audio
* Must have HD audio jack presence detection
* Must have Serial ATA 2.5
* Must have minimum of 50MB NV cache on hybrid HD's with at least 8MB/sec write 16MB/sec read (for mobile only)
* Must support booting from USB flash drives
* Must have Windows Vista Green Button on all remotes
* Must have Green Driver Quality Rating (DQR)
o Green score of 7 to 9
o Yellow score of 4 o 6
o Red score of 1 to 3
----------------------------
I'm really starting to re-considering the Happauge cards at this point. -_-

I guest you didn't read it very well hardware decoding is not the same as hardware encodingLoneWolf15 - Wednesday, June 14, 2006 - link
Mod parent up. He hits every piece of constructive criticism for this article dead on.Good to know about the product, and that Anandtech listens and improves (the nVidia DualTV article was worse) but so much important information was left out of this one.
If the information wasn't available at the time, then Anandtech either should have waited to do the article, or made very clear that this was a very early preview. After owning several ATI TV tuners myself, I know what every ATI xxWonder owner knows --don't buy one until you've heard from others how their Multimedia Center software works, and whether the kinks are worked out. ATI's had a lot of nagging bugs with this software and Anandtech didn't even cover this ground. Add to that the issue of the DRM hardware, quite possibly THE single most important factor in whether Anandtech readers might buy this card or not, and hardly any mention of support under non-MCE Windows versions or third-party products (those that most of us would if we found that Catalyst Media Center sucked) and this article is mostly sizzle, very little steak.
