    looks like it to me
    I installed it on mce 2005 and the picture does not look as good as my
    Samsung SIRT451 High Definition Terrestial ATSC Tuner
    And not many will get this to work in mce 2005 it was a job dont bother with
    it

    I going send it back
    untill microsoft allows for these hybred tuners to work
    its not worth it to have to have 2 tuners and also the sound I have audigy 2
    and 7.1 but the volumn goes way down when you watch any DT channels
    I say DT because thats all you get

    thanks to Robert S for making this work for me
    thanks for you help

    Are you sure you are watching HD Content? I know that when I record HD
    shows (only specific shows usually during primetime) on the HD channels, it
    records 1080i and looks as good as on our 50" TV though the cable box (I
    have both HD OTA and HD over Cable here. HD over cable however does not
    work with media center and primarily works through the comcast cable box).

    Granted, if the channel is not transmitting an HD signal, it won't look much
    better then Standard Def TV. Check www.titantv.com for what shows are
    actually HD.

    Also, I have seen the sound issue as well, but haven't been able to fix it
    yet :(

  3. It should, really - after all, it's _digital_. The DVI output your PC
    generates should be 100% identical to the one a standalone tuner generates.

    Could you be more specific about "does not look as good"? Does the
    resolution seem to be lower? Or do the colors look "washed out" and the
    contrast less?
    Well, have you tried _removing_ the analog tuner now that it is set up?
    What happens?
    You're welcome :)

  4. I don't think there's anything to fix, as this appears to be the intended
    experience:

    http://www.microsoft.com/windowsxp/mediacenter/partners/dfw/decodersreq.msp
    x

    "1.1.1.5 Desktop systems must set the Dolby Digital audio properties to
    default to normal dynamic range (not "Night Mode"). This provides the full
    dynamic range of DVD-V audio and matches volume levels used for the DVD-V
    production. The similar audio levels are used on the Windows Media Audio
    tracks found on Windows Media high definition video content. Laptop systems
    may default to Dolby Digital "Night Mode" for DVD-V audio to provide a
    higher average volume level required for smaller portable systems."

    It appears "Normal Mode" is _significantly_ lower in volume than "Night
    Mode". If you're using the NVIDIA decoder, you can try going to the decoder
    properties through the system tray and switch between "Normal" and "Late
    Night" dynamic range and see that the latter produces higher volume levels.

    Now why the Dolby Digital normal dynamic range is so low in volume will
    have to be answered by someone more knowledgeable than me. :)

    But it's obviously an unhappy experience when the DD audio channels are
    significantly lower in volume than the analog TV channels. Gives a nasty
    blow to the ears when you adjust your volume to a DD audio channel and then
    switch to an anlog TV channel. What were these Dolby guys thinking...? :-(

    well for one way to much red in the picture and its just noway near as clear
    as the standalone and dont forget the standlone has no driver to mess it up
    I am sure that its just drivers but there are no others to try
    I had to put an ehome wonder in and takle out the hauppauge tuner it stop
    working with mce 2005 i guess it never really was right
    well like I thought before i did leave well enough alone
    The picture on mce 2004 was much better with hauppauge tuner and the HDTV
    was way better with the standalone samsung hdtv tuner

    I wonder my my pictuer is so red its worse with dt tv and not as bad with
    cable tv

  7. Hmm, I'd be curious to see this. Could you do the following?

    Start live TV fullscreen, switch to a cable channel, wait for a scene which
    demonstrates the red picture really well and hit the "Print Screen" key.
    You'll probably notice the image freezing for a fraction of a second.

    Then close the Media Center and run the "Paint" application from the Start
    Menu (Start -> All Programs -> Accessories -> Paint). In Paint, select
    Edit -> Paste. You should now see a still frame from the live TV. Select
    File -> Save As, set the type to "JPEG" and enter a filename that describes
    the origin of the picture (e.g. "ABC_cable.jpg").

    Repeat these steps with a DTV channel. If possible, it would be best if you
    could take a snapshot from the same show (provided you have any channel
    both analog in cable as well as DTV).

    Then put these two JPEGs on your website and post a link to it, so we can
    see what you're talking about :)

    had the same problem with this. Robert is correct in that if the HD
    program is in Dolby Digital then the audio will be lower just like a DVD.
    You can use the Night Mode in the DVD Decoders Audio Properties to help
    remedy this. The basic reason is that unlike Analog Broadcast and Music CD's
    the audio in Dolby Digital is not "Compressed" much at all. In other words
    there are more dynamics in the volume to create the appropriate experience.
    This can be quite anoying when changing channels. This is by design and is
    not something Microsoft has done. The same thing would happen using consumer
    component devices.
    In response to this question, I had the same problem using ATI's latest
    driver from their websites download area. They have released a newer driver
    through windows update "only". That resolved my problem. Also make sure you
    have the latest drivers for the Audigy 2. I am also using that card.

    I hope this has helped,
    Mark

  9. Hmm, is it correct that only the first two pictures are from your MCE PC,
    while all the other photos in which your display can be seen show the
    output from your Samsung receiver?

    How are your devices connected? Since you have two receivers (MCE PC and
    Samsung), how do you connect them to your display? Do you use the _same_
    input for both, or does it have several inputs?

    I suspect that your display is simply improperly adjusted for the input
    your MCE PC is connected to. If possible, try connecting your MCE PC to
    exactly the same input your Samsung receiver is currently connected to. Do
    you still get the red picture?

    If this is not possible, check if your display has adjustments, such as
    "tone" or "hue". And try adjusting them to reduce the red.
