<br>Regarding:<br><div><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> The system is a 3.06 GHz P4 running Fedora Core 3. The video Card<br>is a NVidia 5200FX. For capture, all I have is a HD3000. I've checked
<br>that DMA is working on all the drives. I built mythtv from stable<br>source, 0.18.1. I used the following configure options:<br><br>--enable-xvmc --enable-opengl-vsync --enable-dvb<br>--dvb-path=/lib/modules/2.6.12-
1.1381_FC3smp/build/include<br>--disable-firewire --disable-joystick --disable-ivtv --enable-proc-opt<br>--disable-xvmc-vld --enable-opengl-vsync<br></blockquote></div><br>
I have close to an identical system; and I have what is probably
equivalent stuttering. HDTV (live or recorded) is totally
unplayable in myth. I have tried with and without opengl
sync. I can't find the xvmc option in the gui with this myth
version to disable xvmc for testing. Recorded 1080i plays badly
(with frequent pauses and never with audio sync) in mplayer with xvmc
and ffmpeg12mc and plays even worse without xvmc. I'll try
transcoding my latest sample clips to see if they are fine when played
back at standard resolutions.<br>
<br>
I've got <br>
3.06 GHz P4 (which is a 533Mhz FSB chip)<br>
512 MB Ram<br>
BE7-RAID mobo<br>
Nvidia 5200FX<br>
Fedora Core 3<br>
<br>
Night before last's myth svn. No deinterlacing requested.<br>
Prebuffer pauses all over the place.<br>
<br>
I think what we really need is an hdtv playback test suite external to
myth to get better benchmarks on actual system performance. From
previous posts to the list ("well I got *my* P4 1.4Ghz system to
playback hdtv") I think that my system *should* be able to playback
hdtv without issue, but perhaps there are some motherboard weaknesses
or such that make it impossible.<br>
<br>
Very frustrating.<br>
Thanks!<br>
