    Hi Dejjen

    I too have a bad Live TV reception. I used a Hauppage 500 tunder card and
    have a Turion 37 2.0 Ghz processor. My TV is a samsung 40 inch LCD and I have
    a crystal clear normal TV recption...

    Cheers

    Are you sure 1440x900 is the native LCD resolution? If it is, then it's the
    tuner that's producing blurry and blotchy image. Please note that your tuner
    may actually not be at fault. The signal might simply be bad, which might
    have a wide variety of reasons on its turn.

    Also, remember that if you're recieving current-generation analog or digital
    TV, the image must be scaled up bigtime. PAL is 720x576, while NTSC is only
    640x480.

    Start with the simplest things first. Make sure that the coax cable is
    connected properly and that it's not defective. The next easiest fix is to
    try some different resoutions. Try 1280 X 720. I have a Samsung DPL wide
    screen TV that is connected to my MCE computer via a ATI HD Wonder card. I
    also have an ATI 550 Theater Pro card for analog. It took a while but both
    analog and HD are a joy to watch through the MCE computer. What's nice about
    the Samsung TV is that it has a Computer In jack to accept a standard video
    display cable. I also have a 6.1 surround sound connected to the MCE
    computer via the SPDIF port on my mother board and it works great for
    watching DVD movies.

    Trying different resolutions can be dangerous though. I've lost the picture

    Make sure you have the latest tv tuner drivers for your tv tuner card

    The latest beta driver as of today are available here
    http://www.hauppauge.co.uk/downloads/Forum/PVR150/PVR150_24073_BETA.zip

    The latest WHQL'ed driver as of today are available here
    http://www.hauppauge.co.uk/downloads/Forum/PVR150/PVR150_24054_WHQL.zip

    Also make sure you have the latest CPU driver loaded from AMD
    http://www.amd.com/us-en/assets/content_type/utilities/amdcpu.exe

    Since the video output is going through your video card's output, you should
    make sure you have the latest version of that, in addition to the latest
    version of your DVD decoder, whatever it may happen to be.

    If you are trying to watch a Standard Definition TV broadcast which is
    720x480(345K pixels per frame) resolution on a digital display with a
    native resoluton of 1440x900( 1.296 Megapixles per frame) then then your PC
    graphics card or your monitor has to "invent" the content of the additional
    950 pixels per frame. The Picture Quality of your TV video is totally
    dependent on the quality of this upscaling of the display resolution. Your
    display is probably much better suited for use with HD TV signals since they
    are of higher resolution to begin with.
