Installation Procedures

There were a few topics that were so similar among the cards that we wanted to combine them. For all three of these cards, installing the hardware is a relatively simple process. Open the PC, insert the card, plug in the USB receiver, and power up the PC. You can connect or disconnect the coaxial cable at any time without any problems, though most people will probably only want to do that once.

There may be differences in the suggested order of installation. FusionHDTV recommends installing the software before the card, while MyHD apparently needs the card installed before the software installation will fully complete. We managed to get all three cards installed and running using the same process.

First, we installed the hardware prior to installing the software - and we'd recommend downloading the latest software version before proceeding, if you haven't already. After that, turn on the PC and ignore the "Windows has found new hardware" prompts - cancel them. Run the installation utility, and after a few configuration steps and a reboot, you should be done. (You might also get some "This driver is not WHQL certified" warning messages, which you would also ignore. If WHQL certification is important to you, both the MyHD and Fusion5 do not have it.)

After the hardware/software installation, you need to configure the software for your location. We've covered most of this in the individual card reviews, but we wanted to talk a bit more about the channel scans.

That's a list of the digital channels detected by the FusionHDTV software. On both the Fusion5 and MyHD, sorting through that list is extremely tiresome, but it appears to be a necessary evil. You might want to save your channel lineup (and/or write it down) for future reference. The way that you determine what each channel actually displays can vary, and it will almost always require a time investment.

The QAM channel scan turns up a couple hundred channels, many of which are unusable (i.e. encrypted). Out of the numerous channels detected, only about 35 are interesting to most people. All of the encrypted QAM channels can be deleted, as there is no way to watch them. For FusionHDTV, the encrypted channels are clearly indicated. For MyHD, any digital channel that shows a black screen with 0x0 as the resolution and at least a 64% signal rate is almost certainly encrypted.

As is typical of most cable lineups, the remaining channels consist of a lot of junk that you probably don't want, along with the interesting channels. While the analog channels are where you find them normally on your cable box, the digital channels are scattered about on sub-channels in no apparent order. If you get rid of the channels that you know you don't want, you'll probably have 50 or fewer digital channels left to sort through.

To determine the channel lineup, I set the TV to split-screen mode, with the Comcast cable box output on one side and the PC output on the other. (Dual monitors can accomplish this same thing, and you can also reference channel lists on TitanTV or some other site if you recognize the shows.) I chose to get rid of the shopping channels along with any channel that didn't display any content. For the remaining channels, the channel surfer in me had a workout, as I'd tune the card to a channel and then scan through the channels on the Comcast box to find a match. Once a match is found, at least with MyHD, you can label the channel as something more meaningful, like "104 - ABC HD". You might also consider writing them down on paper for future reference - this would definitely be useful when "training" TitanTV on the MyHD card.

While it takes a while, the ability to decode QAM is great for people like me. In fact, you can even connect this card to a standard cable signal and decode the HD as well as the free digital channels, without having anything more than a basic account. (This is assuming that the cable company doesn't put a filter on your line for analog-only subscriptions, which varies by cableco and area.) You might even find a few channels that don't normally show up, though that's subject to change over time. (Watching these "unauthorized" channels also seemed to be one of the factors leading to crashes with FusionHDTV. I could apparently get other subscribers' On Demand movies on at least five or six channels.) FCC regulations require cable companies at minimum to carry the free OTA content, though, so those at least will be available.

    Just to clarify, I'm speaking of overlay mode in general. The MyHD card overlay mode is limited to 720 x 484 reason. It does hardware decoding, which means it's generating the uncompressed HDTV stream on the card. A 720P compressed signal is up to 15 Mb per second. That presents no problem for the PCI bus. Uncompressed 720P, on the other hand, requires more bandwidth than the PCI bus can handle.

    1280 x 720 = 921600 pixels per frame
    4 bytes per pixel = 3686400 bytes per frame.
    60 frames per second = 221184000 bytes per second.

    The PCI bus is a 32-bit bus, running at 33 MHz, giving a maximum bandwidth of 133 MB per second. Uncompressed 720P would require about 211 MB per second. This is one of many reasons that the AGP slot was created. The CPU can render into an AGP cards memory at up to 2133 MB per second, at least in theory.

    So there is a reason that the my HD card doesn't render the overlay mode in anything more than 720 x 480. That doesn't mean I have to like that limitation. :-)

    I don't understand what the point of this review was. Why would you test a hardware based analog card with 2 cards that have software based analog? The addition of the theatre 550 card was completely unecessary and frankly makes no sense at all.

    A more effective test would have put the 2 HD cards up against the ATI HDTV wonder and another seperate test putting the 550 against the Hauppage pvr150 and an Avermedia card.

    Good one

    The review was because I had the cards. We've had complaints about putting out single item reviews. We've already looked at the HDTV Wonder, and it doesn't work for me - no QAM support and I don't want to get an expensive OTA antenna for a rental home. The whole article is a "state of the TV Tuner market" as well as individual card reviews, or at least that's how I intended it. Besides, the Theater 550 PCIe is really just a PCIe version of the PCI card we've already looked at, which is good to know.

    Previous analog tuners have been reviewed, and the ATI HDTV Wonder has also been reviewed. If you can get good OTA DTV reception, you probably have no need for something like the Fusion5 or MyHD. For people like me, though, the choices boil down to forgetting about DTV, getting a DVR upgrade to my cable box, and/or getting one of those two cards.

    After playing with all the cards, I would say your best bet for quality is to get two cards, one of analog and a second for DTV.

    Hey can you include a Mac based HDTV tuner in your round up? The only one I know of is EyETV from Elgato systems and it comes in a form of a breakout box.
  • scott967 - Wednesday, December 7, 2005 - link

    I take it none of these tuners support HDCP on the digital out?

    That's correct, though I may have screwed up when I talked about my TV. I don't know if it has an HDMI or an HDCP port. I thought it was HDMI, but I could be mistaken.

    > Using the Sempron 64 running at 2.50 GHz was more than sufficient for everything but the MyHD analog recording.

    There are no Semprons that run at 2.5 ghz.
  • JarredWalton - Wednesday, December 7, 2005 - link

    I had it overclocked -- I was trying to see if I could get it to work OK for the MyHD card.
  • Olaf van der Spek - Thursday, December 8, 2005 - link

    It may be a good idea to mentioned you were overclocking.
