Hi,<br>I too have an ion based frontend system. I had the tearing problem once but managed to fix it. My problem then were that the screen, as in your situation was shown too big. Therefore I adjusted the screen in mythtv to fit the tv frame. This meant however that every single frame had to be scaled to be shown right on the screen, which with quick changes in the tv content meant tearing. I debugged the problem and found that the X.org log showed that what was sent to the screen was 1920x1080, whiich is my screens native resolution. This meant that it was actually the TV during the upscaling. I have a Sony KVL-52-W4500, and it has a menu entry saying something about pixel to pixel in the image section. By setting that, I could avoid having myth during a scaling which shouldn't have been performed in the first place.<br>
Perhaps this is the same problem for you.<br><br>The RTC timeing issue, i think, would solve any video/sound sync problems. Which I also can suffer from in some cases.<br><br><br><div class="gmail_quote">2011/2/27 Jean-Yves Avenard <span dir="ltr"><<a href="mailto:jyavenard@gmail.com">jyavenard@gmail.com</a>></span><br>

You can't control the volume of a digital interface.<br>
<br>
You can however play on the content stream ; mythtv has a "software"<br>
volume control ; if you use it you will be able to control the volume<br>
<br>
But you're much better off using the TV or amplifier to change the volume<br>
