<p class=MsoNormal>Hi All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve been using myth on and off for a while, and about
6 months ago I settled on ubuntu 9.04 when my<o:p></o:p></p>
<p class=MsoNormal>the linux kernel evolved to the point where my (then 8 month
old) ASUS M3N-H/HDMI was supported.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I can now play TV and Audio through HDMI with the integrated
nVidia ALC1200. My tuner (Dvico Dual Digital4)<o:p></o:p></p>
<p class=MsoNormal>is supported and my LCD (imon) is almost supported out of
the box. VDPAU works really well on the integrated<o:p></o:p></p>
<p class=MsoNormal>nvidia 8300 and even the SP/DIF works. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Everything was fine, until I upgraded to ubuntu 9.10 and
mythth 0.22.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have since had rolling problems with corrupt
recordings. Audio glitches, video blocking and occasionally<o:p></o:p></p>
<p class=MsoNormal>so bad the player cut out.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The physical TV still reported 98% signal, so I was pretty
sure that wasn’t a problem..<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Eventually my fiddling led me to disable my network card, an
AR5416 based Linksys WMP300N. For the last few days<o:p></o:p></p>
<p class=MsoNormal>my recordings have been glitch free.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My system is so butchered its hard to compare to a base
install.... 2.6.32 kernel ... patched lirc ... linux-dvb trunk<o:p></o:p></p>
<p class=MsoNormal>compat-wireless-2.6 (various builds), tweaked dvico
firmware, power management tweaks, sys.vm tweaks etc etc etc..<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The few people I knew in real life who run mythtv insisted I
get a powered splitter, a better antenna, etc ,etc.<o:p></o:p></p>
<p class=MsoNormal>I did eventually get a powered splitter, but of course it
didn’t help.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>/proc/interrupts show no shared interrupts (but it’s
all virtual ACPI interrupts), and removing the driver<o:p></o:p></p>
<p class=MsoNormal>(blacklist ath9k) was not sufficient, I had to physically
remove the card..<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can anyone shed light on why this might be so? Faulty
motherboard maybe? Signal from Wifi affecting<o:p></o:p></p>
<p class=MsoNormal>tuner? interrupt problems? dma problems? What steps
would you normally take to identify such a fault<o:p></o:p></p>
<p class=MsoNormal>when everyone believes its signal related??<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>TIA<o:p></o:p></p>
