I've tried to avoid emailing the list until I was absolutely sure I couldn't get any further without help.<br><br>I'm trying to get a Mythtv frontend/backend server up and running on a P4 2.8 GHz box with 1 GB RAM and Nvidia Geforce 6800. HDTV over firewire is what I'm having trouble with. I can now reliably connect to the cable box and get HDTV streams using test-mpeg2 and in Mythtv itself, however I've been completely unsuccessful at solving my audio stuttering problem. I've tried every combination of settings and every little suggestion I could find on the internet and this list yet I still get the following errors:
<br><br>2005-11-24 04:33:52.663 audio waiting for buffer to fill: have 2048 want 4096<br><br>or<br><br>2005-11-24 04:33:54.567 WriteAudio: Preparing 4096 bytes (1024 frames)<br>2005-11-24 04:33:54.568 WriteAudio: buffer underrun
<br><br>Things I've tried but none have gotten rid of the stuttering:<br>ALSA, OSS emulation through ALSA, an asoundrc is present, Xvmc on/off, deinterlacing (bob) on/off, extra sound card buffering on/off (the TV settings option), agressive buffering on/off (in General settings), priority process on/off, etc, you name, I've tried it.
<br><br>The problem exists in both the current release of mythtv and svn from two days ago. I'm running Gentoo. Does anyone have any suggestions?<br><br>My configure setting:<br>./configure --disable-distcc --prefix=/usr --mandir=/usr/share/man --disable-altivec --disable-xvmc-vld --disable-directfb --disable-audio-oss --disable-directx --enable-firewire --disable-audio-jack --disable-joystick-menu --enable-lirc --enable-xvmc --enable-opengl-vsync --enable-xv --enable-x11 --enable-proc-opt --disable-dbox2 --disable-ivtv
<br><br>Also of note, I'm using a PCI firewire card that has a VIA chipset. Some have said there are issues with these, but I dont think its the source of my problems since I'm able to grab streams fine using test-mpeg2 and they playback perfectly in mplayer using xvmc. My motherboard is a SiS chipset.
<br><br>Any help would be awesome, I'm about at my wits end and starting to look at other platforms, but really would like to stick with myth if possible. Thanks.<br>
