Thanks for all the help!<br>
The conclusion is for now:<br>- decoding this flavour of H264 in MythTV is not yet fully correct<br>- the decoding is a problem of ffmpeg and not of MythTV<br>- only one core is used in decoding<br>- when ffmpeg decoding for H264 is fixed then we need the fastest processor there is for this content<br>
- when ffmpeg is not only correct but also multithreaded so that it uses all cores of a dual- or quadcore then a cheaper/low-power processor can be used.<br><br>Again, thanks for the testing and the clarifications,<br>Klaas.<br>

</div>I've just tried this with MPlayer SVN r26779 on an Intel T2400 and it<br>
struggles to play. Also I'm seeing the interlaced artifact issues due to<br>
the partial interlaced PAFF support in FFMPEG.<br>
