Thanks Matt, that was very helpful. At this point I've upgraded my BIOS, which may have helped. I can now manually change the IRQs in the BIOS. However, two of them will continue to share one IRQ, I assume these are the two 150s on the PVR500. However, I think that the issue was caused by one of the tuner cards sharing an IRQ with my Nvidia card, which I was able to move to a different IRQ. So, now I have 4 tuners (on 3 cards) which all play audio and video. However, /dev/video2 & 3 (PVR500) stretch the screen so I can only see the left side. I made sure to set them to 720x480 capture, as per Jarod's guide. However, when I run the command that you mention above (ivtvctl -a -d /dev/videoX) each card shows that it is capturing at 480x480 (after a reboot). Using 'ivtvctl -f ...' I set the cards back to capture at 720x480 and it worked! All four tuners now show GOOD video and have audio as well. Then I restarted Mythbackend, and was right back where I started. So, it looks like this issue is almost solved (Thanks guys!). Now I just need to know where to set the capture resolution in MythTV, I think... -- Garry _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
