thread 0.18.1 was causing this problem for that person).
Anyone else finding black flashes when using both the encoder and decoder
simultaneously on a 350 with 0.19?

At the time it seemed like a very silly mistake to be blaming myth for
that problem. However, after seeing this thread on the ivtv-devel list
( <a href=3D"http://www.gossamer-threads.com/lists/ivtv/devel/24487?page=3D=
last">http://www.gossamer-threads.com/lists/ivtv/devel/24487?page=3Dlast</a=
> ) it
looks like I might be back here again soon :-) as they point the finger
at myth's use of overlays.<br>
