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.

She actually. ^__^The one thing that really irked me over the 550, which pretty much forced us to go with the X1800 AIW instead, is that without MCE 2005 it was not a very useful card. Heck, we did'nt even have the fallback of the Multimedia Center, which a lot of us who have had either ATI AIW or their stand-alone TV tuner learned to live with, and instead got shafted with the terrible bundled software. :P I mean, come on, if you bundled the nice Adobe software with the AIW why not at least do it with your tuner cards instead of pawning off the third-rate discount bin stuff?
In either event I'm hoping that whoever did this article re-labels this one since this is definatly NOT a review in any sense of the term.

Ouch! I'm so sorry. No disrespect intended. :)
That's why at the time I went with a Hauppauge WinTV PVR-150. My TV Wonder PCI is fine for just watching (provided you use very specific versions of ATI's MMC software, as some have seriously broken the audio setup in their push to go from analog to digital across the PCI bus) but all the software solutions I saw were most compatible with Hauppauge boards at the time over the Theater 550. In fact, GB-PVR, my personal favorite, is great when paired with any PVR-xxx card. Bonus: it's free.
I got a ReplayTV on the cheap with a lifetime subscription, so I dismantled my HTPC. Still, I'd love to replace my TV Wonder with a good card for casual use in my main system. With the lack of information on DVR and Catalyst Multimedia Center, this card won't be it. And I'm in full agreement of you that this article does NOT constitute a review.

I fail to understand why you think its acceptable to leave out the DEFACTO capture card. AGAIN. Hauppauge is the clear industry giant in video capture, and you publish another article, flippantly referencing us to your previous review of the card. Image quality is subjective, and its important to allow us to see, and judge, the image quality instead of your "just trust me" attitude.Leaving hauppauge out of a capture card review would be like reviewing ATI's latest video card, and comparing it to SIS instead of nvidia.

One disappointing *feature* I discovered on my Theater 550 PCIE that is EXTREMELY IRRITATING is lag with the video in ports. I tried hooking up a game system to it, and if I hit the jump button for example, I would have to wait a little bit for my character to jump. I'm not talking anythign like either, I'm talking extremely noticeable. Itried contacting powercolor help, and they said update drivers (already did) and somethign else, and then quit responding to me. Is there anyway that this can be tested as if I would have known this ahead of time, I don't think I would have purchased it.nvmarino - Wednesday, June 21, 2006 - link
If you want to connect a game console to your display via your PC you want one of these:http://www.simplifidigital.com/shopsimplifi/index....">http://www.simplifidigital.com/shopsimp.../index.p...
As others have commented, tuners cards (especially those with hardware encoders) are not designed for this.

I agree, I had to get rid of my Theater 550 setup (and seems 650 is as bad) and swap back to a 7year old Brooktree 878 based TV Capture card due to the lag. The BT878 has a delay of about less than 100msec, its excellent.I have to use the Svideo Input on TV Cap Cards as the Satelite TV service here (Sky "Digital") uses encrypted signals that can only be decoder on their decoder box. Once you decode it, you can output the raw video signal (SCART RGB to Svideo adapter). I then input this into DScaler. Image quality was a bit better on the Theater 550, however the lag was unusable.
From the article it seems the lag isnt just on the Video Inputs, but the TV Tuning too, so contary to the other reply, seems everyone will notice it. Cant understand how a 2000msec delay is considered "ok" for product release.

"Cant understand how a 2000msec delay is considered "ok" for product release."These types of TV cards are designed for watching TV (not video games) and specifically for timeshifting/recording TV using a PVR application with a built in TV Guide, so channel surfing isn't necessary. For that purpose a 2 second delay doesn't really matter.
What you want is a transcoder, which is a different beast altogether.

That is because it has to encode the signal. You aren't supposed to use it as a video input to your computer for consoles.Crucial - Wednesday, June 14, 2006 - link
Your choice to not include the Hauppage cards was a slap in the face of everyone who asked for them and nothing short of a joke. The Hauppage cards are by far the more popular product and it would make more sense to compare them for those of us who might buy the new card if they infact are better. If your video card reviews followed the same pattern as your tv tuner reviews you would be the laughing stock of the internet. We want a screenshot of the apple, pattern and girl on a hauppage card to see for ourselves which card looks better. I'm guessing the couple of years old pvr150 would look better than all of them and ATI wouldn't let you show it. If not then do a couple more tests and update the review.As for the DTV portion of these cards, I'm sorry that you don't get DTV reception in your area but I couldn't care less. Millions of us do and use it. If Anandtech is going to be a top quality review site they need to find a reviewer who can get it. Important things to know about the DTV would be can a digital and analog channel be recorded at the same time? What kind of cpu usage does the tuner use when recording both or watching an analog and watching a digital? Can MCE use 2 of these cards and record 2 analog and 2 digital channels at once?
Each time I see these reviews I hope you change you tune and do a real comparison of whats out there and being used instead of being the puppet for the corporation thats giving you free product to play with.
