<p>The current dshowhelper can cause stuttering/dropped frame problems with H.264 video streams which use mixed field/frame (interlaced/progressive) encoding e.g. UK Freeview HD TV channels. The stuttering occured at the points when the encoding mode switched, which can be quite frequently (every few seconds).</p><p>It's become a much worse problem with very recent versions of LAV video decoder since they respond differently to these streams by causing 'RenegotiateMediaOutputType' requests to be generated at the interlaced/progressive switching points.</p><p>Github branch with fixes included - <a data-cke-saved-href="https://github.com/MediaPortal/MediaPortal-1/tree/MP1-EXP_dshowhelper_MP160_Owlsroost" href="https://github.com/MediaPortal/MediaPortal-1/tree/MP1-EXP_dshowhelper_MP160_Owlsroost">https://github.com/MediaPortal/MediaPortal-1/tree/MP1-EXP_dshowhelper_MP160_Owlsroost&lt;/a&gt;&lt;/p>
