[QUOTE="mm1352000, post: 1153952, member: 82144"] Strange. :S AFAIK your GPU and CPU are quite weak. Therefore your system may struggle to display h.264 1080i video successfully. When you disable deinterlacing, you reduce the load on your GPU (or CPU, depending on configuration). The load reduction is probably enough to allow successful h.264 decoding (ie. "smooth live tv video playback"). You have to configure video decoding (DXVA, deinterlacing, post-processing, anti-aliasing etc.) very carefully in order to balance the load on the GPU and CPU and avoid overloading. No surprises there! This is because you have disabled deinterlacing. Deinterlacing removes those "horizontal lines". If you disable it then the horizontal lines will not be removed.
