couldn't handle HD. I've noticed that any files with an AC3 audio<br>
stream have stutter and jumpiness; which dramatically increases after<br>
using the skip forward or skip back functions in mythfrontend.<br>
<br>
The thing is that I'm only using the stereo-out jacks, and not the<br>
digital out features of my sound card.<br>
<br>
I've read from some other threads that this HD choppiness might have<br>
something to do with a 32kHz to 48kHz conversion that mythfrontend<br>
does internally? This might indeed be the case, because when I play<br>
recordings directly from within xine, everything sounds and works<br>
well.<br>
<br>
If I disable the onboard sound card (in the BIOS), or set mythtv to<br>
output to NULL, video is smooth (but obviously I can't gauge audio,<br>
because there is none). The problem persists when I changed the<br>
soundcard to a PCI one. It also persisted when I used the Mythbuntu<br>
Live CD on completely different computer, a Gigabyte GA-965P-DS3 with<br>
a Core2Duo.<br>
<br>
Any ideas?<br>
<br>
Here are the specs:<br>
<br>
MythTV-0.21-fixes (from ATrpms)<br>
Mythbuntu 8.04.1 (also tried with CentOS 5.2 and Fedora 9)<br>
AMD Athlon 62 X2 5000+<br>
2 GB RAM<br>
GeForce 7200GS<br>
Gigabyte GA-MA78GM-S2H (AMD 780G)<br>
<br>
Thanks!</blockquote></div><br><br>I say this to everyone, try and delete (rename) ALSA.conf and .asoundrc<br>There are defaults that work fine.<br><br>Allen<br><br></div>
