    Hello guys,

    I have a small problem regarding my config. Tried all and everything now but it seems that I can't
    get HDTV to work properly.



    I switched to the Cinergy S2 card a few days ago. With the old card I was ble to watch normal TV flawlessly.
    Now with the new one I get artifacts and stuttering from time to time. (Normal TV that is)
    Adusting the dish a bit helped some but hdtv still stutters like hell (That with 98%Quality and 93% Level on the Dish)
    Currently I'm using the Cyberlink h264 codec. Changing the codec to ffdshow for h264 doesn't work. I just get a blank picture.
    h264 movies play like a charm with both the ffdshow and the cyberlink codec. I'm totally out of any ideas at the moment. Maybe someone has a solution for my problem.
    I heard that sometimes older LNC's cause problems when it comes to play HDTV content ? How can I check this ?

    hi reve, i suppose your integrated video card causes the trouble. i bet it cannot handle the load of the tv stream.
    have a look at the taskmanager during hdtv watching an compare to sdtv. so you'll see...most likely...that your cpu has to do the work which the inbuilt video card isn't able to manage.

    so buy at least an ati 2400 or 3450 better 2600pro ( depending on the height of your enclosure) and your problem vanishs.
