[mythtv-users] widespread reports of (sort of) the same failures

1) I have not raised this on the ivtv board.  I can go back to previous 
versions of the ivtv drivers and the problem remains.  I took this to 
mean that it was not strictly an ivtv issue, but more likely some 
compatability issue.  I have tried many, MANY versions of ivtv with 
little change.

2) perhaps I can increase the ivtv debug output.  I will check and try it.

3) don't know what happens if I reload all of the kernel modules.  I do 
know that if I restart the mythfrontend, then all is well again for 1 
pass through the video startup, with an error introduced on the second 
pass.  To me, this again points to mythfrontend.

in any case, thanks for the response.  I had given up on this request.
