Thanks for that article. Very interesting to me.
I just looked at my IRQ assignments and IRQ 11 is being shared by
usb-uhci, via_v4l, eth0 on my EPIA M10000 (mythfrontend only)
now I'm wondering if that could be an issue.....I get occasional
"Prebuffering Pauses", using the opensource drivers for hardware
decoding.
