I'm still reading it.  ;)

I see the same flickering artifact of what looks like parts of the current
frame in my recorded programs.  Not sure about live tv, I don't use it much
ATM.  I see this playing back in Myth and also with WMP via MythWeb on my
WinXP box, so It would seem to be an ivtv driver issue on the capture end.
I'm using a PVR-250 on a PII-350 for my backend, running 0.15.1 on FC1 with
everything updated from Axel's rpms.
