Hi all. I have recently built from scratch a new system for play myth SD and HD content frmo a DVB-S source. <br><br>The system is a dual core AMD Athlon64 6400 @ 3.2 ghz, with 2 GB RAM, ATI 690G chipset.<br><br>The system seems to work great for playing SD content, which it can due utilizing around 20% of one CPU.<br>
<br>But to my surprise it can't seem to handle HD content. No matter what decoder or deinterlacer I select, I get up to 95%-100% CPU, and the system starts choking.<br><br>Now, tome, this seems crazy. I know in Windows this system can handle playing 20 Mbps HD content without a hiccup. So my questions:<br>
<br>- Is this CPU even enough for playing back DVB-S HD content? It should be I would think<br><br>- Are there any compile flags you can pass to ./configure that would significantly impact anything?<br><br>- When you are in mythtv-setup, there is an option to set the max CPUs for decoding, yet AFAIK myth only EVER uses one cpu. Is there some special compile option or codec I need to choose to allow for multi CPU decoding? 50% of each core would be much better than 100% of one.<br>
<br>- Could my bottleneck actually be the ATI video card, which I know already has some tearing issues? 'top' is reporting mythfrontend consuming all the CPU, not X.<br><br><br clear="all"><br>-- <br>In theory, there is no difference between theory and practice. But, in practice, there is.<br>
