Alright, I have been struggling (tolerating, putting up with, etc.) the<br>playback performance regression that got introduced with 0.19. It seems<br>that a lot of people here have observed the same thing.<br><br>I don't know what happened between
0.18.1 and 0.19, but the _only_ thing<br>I did was upgrade the myth software packages on both my BE/FE machine<br>and a standalone FE to 0.19 and since that upgrade both of the FE's<br>suffer 100% CPU usage and the associated stutters in playback. Both of
<br>these systems used to playback perfectly smoothly with 0.18.<br><br>This sounds like what a lot of people have been complaining about so<br>let's explore why this has happened.<br><br>As for my set up, both machines have an nVidia 5200 card in them. Both
<br>are SDTV on composite outputs. Both run the 7676 nvidia driver. Both<br>use Bob de-interlacing (much to my chagrin because a decent output<br>device like the G400 doesn't need it -- crappy nvidia 5200's apparently<br>
do need it). Other hardware specs are irrelevant since I am comparing<br>playback performance on the exact same setups with the only change being<br>from Myth 0.18.1 to 0.19.<br><br>I don't want to get into checking this this setting and tweaking that
<br>setting because the root of this problem has to lie in the myth playback<br>code. It is the _only_ thing that has changed here.<br><br>Additional evidence of Myth's poor playback performance is that using<br>mplayer or xine on the exact same hardware _always_ plays back without a
<br>blip.<br><br>There is something wrong in the myth playback code, let's find it!<br>Please?<br><br>b.<br><br>--<br>My other computer is your Microsoft Windows server.<br><br>Brian J. Murrell<br><br><br>-----BEGIN PGP SIGNATURE-----

</a><br><br><br></blockquote></div><br>Although Brian might have been a little to strong in pointing out that his problems are for sure with Myth I am having problems playing HD content inside of Myth but can play the same content with xine and don't have any problems. I am making sure I have everything setup correctly now but my processor is not maxed out and it does great in xine with the same hardware so it sure does look a little funny on the Myth side. I am definately not complaining though I am happy to get what I can get and I am running some of the latest svn. Just thought I would add what I noticed to this.
