    Hey Guys,

    I recently tried W7 Media Center when I upgraded to W7 to see how it performs these days. I am now back in MP land, but have found an interesting issue.

    The morning news show I watch has a "ticker" scrolling headlines etc. along the bottom of the screen. I never noticed an issue until I moved to media center. In MediaPortal the scrolling ticker looks blurry, as if the scrolling text leaves a shadow after each letter. In media center it was very VERY clear.

    No hardware has changed, so I assume it is MP. Could this be the TS reader/writer, or is it more likely to be the renderer that MC uses vs what MP uses? I haven't added any codecs above what W7 installs, nor have I changed the default codecs in MP config.

    Any thoughts?

    Seems to me you have SAF installed (or have manually installed FFDShow and LAV), so you did install 3rd party codecs ;)

    Anyways, is the problem you see on MPEG2 or MPEG4 channel(s)?

    What is your Windows-refreshrate and your TV's refreshrate?

    Logs after playing TV with the problem showing would be the best way to get any more specific help...

    Hi metalla_nz

    You didn't mention what channel you're viewing, but either way the streams from Optus D2 and D1 (Freeview, Sky) are digital MPEG 2 - the blurriness will have nothing to do with TsReader or TsWriter. If you like the quality of the image produced by MC then use the MC video codec in MP. Set the MPEG codec on the TV tab in the codecs and renderer section in MP configuration to Microsoft DTV-DVD video decoder. If you still experience problems then it is possible it is caused by deinterlacing algorithm/quality or refresh rate matching as suggested by Pilehave.
