Sir Hans, have you or will you in the near future have a chance to look into the causes of the above DMA errors? These errors cause corrupt video and audio from the point when the message starts until the system is rebooted (rmmod/modprobe ivtv doesn't help). I just did a mass cleaning and upgrade of my FC4/myth box with the latest updates and atrpms, etc. It didn't help to bump the PCI latency up on the card via "setpci -v -d 4444:0016 latency_timer=b0". Happens on the NForce4 (AMD 4400+) and NForce2 chipsets, but doesn't seem to happen on a Dell 4600 Intel 2.4/HT/SMP chipset (a bit too slow for good HD playback). Reverting to PIO mode loads the box to the point you can't watch while something is recording (AMD 3400+), but does give good recordings. Let me know how I can help, if at all.
