Hello,
I have a FC3 based system with dual PVR-250s, and everything was working just fine for several months.
Then something happened. I'm not sure what. The PVRs just stopped working correctly
I fiddled around, switching the PVRs around into different PCI slots. I was never able to determine that either card had gone bad using this musical chairs scenario. That is, there was no rhyme or reason to what card would work in what slot, so I thought maybe the MoBo went bad. I replaced the MoBo with a new copy. That didn't seem to help.
I swapped out the power supply, too, just in case. That didn't help.
So, where it stands now is... if only one PVR is installed in the system, it just does not work. Neither card. However, If I install both PVRs, one of them works and the other doesn't.
By "work", I mean mean the test video capture via cat /dev/videoX > test.mpg, then playback via mplayer, as described in Jarod's guide: http://wilsonet.com/mythtv/fcmyth.php
FYI, I was able to run these same tests with success 2 months ago, so I'm pretty sure I am doing it right.
When both cards are installed, only one works and the other produces static. If only one card is installed, and it doesnt seem to matter which card or which PCI slot, I get static.
Where can I find documentation describing the possible ivtv driver settings that go into modprobe.conf?
What ivtv diagnostics tools are available to help me isolate the cause of this problem?
Any ideas appreciated,
Larry
